Straight Talk
Never assume anything Mike Mavrigian | Editor
O
(i.e.: you get what you pay for)
ne of the frustrating aspects of performing automotive service work is occasionally dealing with a faulty new part. Leading parts manufacturers have an excellent track record of quality control, but sometimes a bad part slips by and ends up in a box that’s sitting on your local supplier’s shelf. Not surprisingly, that potential is much higher with really cheap, no-name, bargainbasement imported parts. High quality, brand name parts are imported from all around the globe, and there’s no confusing them with the questionable “bargain” import parts. Those parts are cheap for a reason. As a case in point, my shop recently restored a 1968 Plymouth B-body car. One aspect was a complete restoration of the heater box assembly, which of course houses the heater core. The customer, wishing to save a few bucks, purchased a new heater core at an astonishingly low price. (Before you jump on me, I know, we should never have allowed the customer to give us the part!) Assuming the heater core was new and fault-free, one of my guys installed it into the housing and reinstalled the heater box assembly prior to installing the dash and windshield (at a time when access was easiest). Once the engine was fred, we noticed a considerable coolant leak. Luckily the carpet wasn’t installed yet, as coolant
spewed from the heater core and collected onto the passenger foor. We should have tested it before installation, but when it’s brand new, we assumed it was OK — and you know where that led. To make a long story short, we pressuretested the system and found the leak at the heater core. At this point, hours were wasted by removing the heater box assembly (we weren’t about to remove the windshield and dash at this stage). We removed the heater core from the box, tested and confrmed that the tubes in the core were leaking via a series of substandard brazing points and pinholes. We purchased a new heater core from an established manufacturer, pressure-tested it before installation to verify that it was good, and fnished the job. The new heater core cost about $100 more than the “inexpensive” unit purchased by the customer, but it was fawless. The customer paid for the new part, but we didn’t charge for the extra time that was wasted. (I know we should have, but I felt bad for the guy.) Lessons learned: 1) Whether the part is electrical, hydraulic, plumbing-related or mechanical, inspect and test (where possible and practical) before investing in installation time. 2) Explain to the customer that “you get what you pay for.” 3) Don’t assume anything, and always try to go for the “premium” part, in those cases where you have a choice. ●

Tech tips From a Navistar turbo to Audi fault codes FORD TURBO MYSTERY Do you believe in magic?? What else could account for the operation of the high pressure oil system on Ford’s power stroke diesel? This much I can assure you — it was not designed by Harry Houdini, but hey, maybe a distant cousin?! What I do believe is that the oil system used on this engine is an engineering marvel! While space limitations won’t allow me to babble on endlessly, hopefully this tech tip will give you a better understanding of how this system works. When the engine is cranked over, crankcase oil pressure builds. In addition to lubricating all of the engine’s internal moving parts, the oil has one more path to follow. It travels through the timing cover to a high-pressure injection reservoir mounted on top of it, used to supply oil to the high pressure oil pump. This pump then increases the pressure to the high levels needed to pop open the injectors, and to increase the pressure of the diesel fuel entering the cylinders for complete combustion. The oil pressure increase is accomplished by a solenoid similar in function to an idle air control valve. This solenoid, the injection pressure regulator (IPR), is duty-cycle controlled by the powertrain control module (PCM) to boost the oil pressure to the levels needed for good performance. The oil then fows from the pump through braided steel lines to the center of each cylinder head where it runs through a central galley next to the injectors. When the PCM determines which cylinder needs to fre, it electrically energizes a solenoid in the injector to allow the high pressure oil to enter, intensifying the pressure of the diesel fuel and injecting it into the cylinder. The PCM uses an injection control pressure sensor (ICP) to determine what the oil pressure is. The sensor is mounted

in the inside face on the driver’s side. The more ground time applied to the IPR, the higher the pressure rises. The minimum amount of pressure needed to open the injectors is 400 psi. With a pump designed to put out well over 3,000 psi, the PCM should be able to achieve that pressure with no more than a 12% duty cycle on the IPR. If the ICP indicates pressure fails to reach the minimum value, the PCM continues to increase the duty cycle on the IPR until it reaches the maximum of around 60%. Somewhere around 50%, even if adequate pressure is achieved and the engine runs, the PCM sets a code for ICP above/below normal. The frst step in diagnosing a fault in this system simply requires checking the oil level in the crankcase. If the oil level drops three quarts or more, it lowers the level in the high pressure reservoir, reducing pressure in the injection oil system. Once oil level is verifed, watch the engine oil pressure gauge on the dashboard while cranking to verify that it jumps to the middle in a short amount of time. In real life, this “gauge” is an “idiot light” with a needle. It uses a normally open switch instead of a true sender. When engine oil pressure exceeds 5 psi, the switch closes, completing a path to ground for a voltage applied through a dropping resistor in the gauge, causing the needle to jump up. This switch is located in the top of the high pressure

The Tech Bench reservoir. If engine oil pressure for any reason is low, it will need to be addressed frst as insuffcient high pressure will result. If it is OK, monitor the rpm, ICP and rpm PIDS in the datastream with a scanner. Upon cranking, at least 150 rpm should be noted. The PCM then activates the IPR to build pressure. If the IPR reaches the max and under 400 psi is showing on ICP, or you see a reading of 2,000 psi to 2,500 psi (a default reading generated by the PCM when it believes the sensor is in error) and the engine doesn’t start, there is a fault in the high pressure system. To isolate the heads as a potential large leak: 1. Remove the line from the right head and cap with a suitable plug. 2. Remove the left hand line and adapt an oil pressure gauge capable of reading 3,000 psi or greater to it. 3. Crank the engine while watching the gauge for actual pressure. If the reading is low, the problem lies in the high pressure pump or the IPR. But to determine which is the guilty culprit, you frst need to replace the IPR to evaluate. If that doesn’t correct it, the pump will need replacing. So the next time one comes in with a lack of power, stalling or no start concern and you retrieve fault codes P1211 and/or P1212, you, too, can work a little magic!

AUDI FAULT CODES This tip applies to fault code 65535 or 00003 stored in the fault memory of a control module in 1998 to 2010 Audi A4 Quattro vehicles. 1. Fault codes 65535 and 00003 indicate an internal issue with whichever control module the fault code came from. 2. Before condemning the control module outright, it is best to do a bit of diagnosis and cover all the bases. 3. An issue with the battery or charging system has the potential to set this fault
code. A. If the battery voltage drops below 9.5V or spikes up over 15 to 16 volts, this fault code can be set. Be sure to check the battery for a good standing voltage and that it performs well under a load test. B. If the alternator is not maintaining battery voltage or is putting out excessive amounts of AC ripple, the fault can be set. 4. Be sure to verify power and ground into the specifed module before condemning the module. If there is a power supply issue, the fault code can be set. A. Be sure to check for the power and ground in a loaded state. (i.e. take a sealed beam headlight or similar device that will draw a large load on a circuit, power the device through the power Don’t condemn the control modand ground ule on Audi A4 Quattros due to fault codes 65535 and 00003. supply and verify that while the load is on, B+ and ground are still present). 5. A freezer test can go a long way in determining internal control module issues. A. Put the specifed module into the freezer for 30 minutes. If the fault code does not return right away or waits until that module reaches its ambient temperature again, this would indicate an internal fault in the control module. B. The same test can be done with heat. Gently apply heat with a hair dryer or heat gun and see if that makes a difference in how the fault code clears. (NOTE: Be careful not to overheat the module and fry the internal circuits.) 6. If power and ground are present and the battery and charging systems are working OK and the fault code changes (comes and goes) with the temperature of the module, then the issue is inside of the module.

NVH revisited
Correcting concerns relating to vibrational issues By Mike Mavrigian
N
oise, vibration and harshness (NVH) issues are certainly not limited to wheels, tires, brakes and steering/ suspension areas. Engine faults (misfres, rotating assembly balance, etc.), worn or damaged engine mounts and driveline issues (driveshaft, transmission and drive axle) are all potential contributors to NVH concerns. In this article we’ll discuss a variety of NVH issues along with tips to avoid and/or cure these ills, with an emphasis on chassis-related areas.
SHIMMY Wheel shimmy (steering wheel right/left oscillation) can be caused by a number of variables. Follow an organized step-by-step inspection:

1. Inspect the tires for excessive and
uneven wear, and inspect for tire structural damage (badly deformed sidewall, etc.). Poorly constructed tires or damaged tires where plies are misaligned or separating can cause a shimmy/vibration. Check the tire and wheel for proper bead seating along the entire bead circumference on both sides. An improperly seated bead will create a radial runout condition. 2. Inspect and adjust tire infation pressure. Low or uneven pressures on the same axle can cause pulls or wander. 3. Check for lateral runout. Using a dial indicator at the wheel rim, slowly rotate the wheel (on the vehicle) a full 360 degrees, noting maximum lateral runout. If excessive lateral runout is found, don’t automatically blame the wheel, since runout may be the result of hub or rotor runout and/or a stack-up of tolerances between the hub, rotor hat and wheel.
The brake alignment shim is placed between the hub and rotor, oriented to correct lateral runout.

BALANCING TIPS Centering of the wheel, both on the balancer and the vehicle hub is critical. If incorrectly mounted on the balancer, a precision balance won’t be possible. By the same token, a wheel that is correctly centered (and balanced) on a dynamic balancing machine won’t be able to duplicate the balance (and road force variation variable) if incorrectly centered onto the vehicle hub. Most wheels are mounted to a balancing machine with a tapered cone that centers the wheel onto the balancer’s shaft. Cones are available with different tapers.
Cones that feature a low taper are preferable to better center the wheel. Back-cone mounting is preferred (where the cone mounts from the backside of the wheel). However, some wheel designs will not center using back-cone mounting. In these cases, front-cone mounting is required, where the cone centers the wheel from the outer side of the wheel. When using the back-cone method, once the clamping cup and wing nut secures the wheel, depress the foot pedal to hold the spindle in place, and slowly roll the wheel

4. Before removing the wheel/tire assembly, with the suspension unloaded, check for wheel bearing looseness by rocking the tire inward/outward at the 12- and 6-o’clock positions. 5. Remove the wheel/tire assembly and inspect the wheel fasteners (studs and nuts or bolts, depending on design). Damaged threads can be an indication of abuse/over-tightening which can contribute to wheel/hub distortion. 6. Inspect the mating faces at the rear of the wheel, rotor hat and hub face. A buildup of corrosion can cause a lateral runout condition. Clean all surfaces. 7. Check for lateral runout at the hub itself. 8. Inspect the wheel rims for damage (bent rims, signs of pothole/impact damage). 9. Check/adjust each tire/wheel assembly for dynamic balance. 10. Inspect the entire steering and suspension system. Looseness (caused by wear, damage or improper installation) can contribute to a shimmy, in addition to wander and directional pull. 11. On the alignment rack, measure all angles, paying particular attention to caster angles. An excessively positive caster (caster angle beyond factory specifcation for the specifc vehicle) can promote a shimmy condition. 12. During reinstallation of wheels to the vehicle, always use a torque wrench and follow both the specifed torque value and tightening pattern.

towards you during initial tightening of the wing nut. This helps the wheel to roll up the taper of the cone, instead of trying to force the wheel to slide onto the cone. When using the front-cone method, pull the top of the wheel/tire away from the hub face while tightening the wing nut. This will help to overcome the force of gravity and improve wheel centering on the machine. • Verify wheel centering on the vehicle. • During tire mounting/infation, if infation limit is exceeded, defate, loosen tire bead and re-infate. • Match-mount tire to wheel using balance/high spot dots where available.

HUB-CENTRIC AND LUG-CENTRIC WHEELS The terms hub-centric and lug-centric refers to the manner in which the wheels center onto the hubs. If the wheel relies on centering at the hub, it’s hub-centric. If the wheel relies on centering by the fastener locations, it’s lug-centric. If the wheel is not centered onto the hub, radial runout will occur, resulting in a vibration/bounce. Some aftermarket custom wheels that are designed for hub-centric centering may be made with a large center hole that will accommodate the largest hub in a certain vehicle application. In order to adapt the wheel (and retain centering), hub-centric rings are required (for example to reduce the hub hole from 88 mm to 72 mm, etc., in order to center onto another vehicle make/model. If the hub rings are not installed, and the wheel center hole is larger than needed for the hub in question, you can’t necessarily rely on the fastener locations to properly center the wheel on the hub. Multi-pattern wheels are available in the aftermarket, designed to provide a ftment
to more than one bolt circle dimension. While some of these wheels feature multiple bolt holes (for instance, 10 holes where the application is intended for a fve-bolt hub), some multi-pattern wheels feature oblong lug holes, designed to accommodate more than one bolt circle. Instead of the holes being round, they’re oval shaped, allowing mating to likely two bolt circle diameters. In theory these wheels should be hubcentric so that the wheels are properly centered to the hubs. These wheels are not very common today, but if you encounter them, extra attention to wheel centering is a must. After mounting to the hubs, check for radial runout (visually at frst, then with a dial indicator). Inexpensive aftermarket wheels may feature slightly oversized bolt holes and oversized center holes, which can easily create a radial runout condition, resulting in a “thumping” vibration. Check hub-to-wheel centering, to verify that the clearance is even and within the target value of 0.004 inch (0.1 mm) maximum. If the clearance is out of spec, rotate the wheel (wheel clock position relative to the hub). If the clearance is still out of specifcation, check the hub for runout to determine if the condition is in the hub or the wheel. While we’re considering wheel centering, it’s important to note that if the wheel is centered improperly on the balancer, and installed properly centered on the hub, or if properly centered on the balancer but improperly centered on the vehicle hub, a vibrational problem is bound to occur. If the wheel does not provide a precise “slip ft” onto the hub (being centered by the hub/hub-centric), extra care needs to be taken to center the wheel during installation. This situation can be common for some budget level aftermarket wheels.
WHEEL BEARINGS/HUB BEARINGS Use a dial indicator, mounted to a solid, nonmoving component, to check for rotor lateral runout. Secure with lug nuts prior to measuring.

The Chassis make proper wheel alignment impossible. Always check wheel bearing condition prior to any alignment work, and be sure to measure hub fanges for lateral runout. Note that some bargain-basement-priced hub assemblies may feature short-lived bearings and may feature excessive lateral runout. High-quality, precision-made hub assemblies produced by reputable makers offer higher quality bearings and tighter runout tolerances to avoid NVH issues.
When the piston(s) in a disc brake caliper are forced outward against brake pad backing plates, the frictional heat generated naturally transfers into the caliper and the hydraulic fuid, elevating fuid temperature. In addition, if the pads are not perfectly aligned to the rotor disc, a harmonic vibration generates which results in a pad “squeal” and potentially a pedal bounce. A trick to address both of these issues is available in the form of Nucap US Inc.’s “piston cushions,” lightweight and thin discs that snap into the pistons, creating an

with 0.005 inch nitrile rubber. The cushions serve to absorb vibration, which reduces or eliminates annoying brake noise, and acts as a thermal barrier to reduce heat transfer to the brake fuid. In addition, the cushions provide protection to the caliper pistons in terms of reduced wear and heat transfer. Installation is simple. The correct shim size is selected from the kit to accommodate the piston’s inside diameter and wall thickness. A provided lubricant is brushed onto the rear side (piston side) of the cushion. The lubricant is applied simply to allow the nitrile rubber facing to move a bit to prevent it from sticking to the piston. The cushion is then inserted into the piston via locating tangs. The foating design of the cushion, in addition to the vibration absorbing characteristics, absorbs pad vibration and reduce heat transfer.
The cushion, which absorbs vibration, simply “snaps” into the piston and is designed to free-foat. A small amount of lubricant is applied to the piston-side of the cushion to retain the free-foating characteristic.
CORRECTING FOR DISC BRAKE LATERAL RUNOUT If the brake rotor-to-hub interface is not perfectly aligned, deviation in surface thickness of the hub and/or rotor hat will result in a lateral runout condition of the brake disc. This lateral runout will cause the brake pads to bounce against the brake disc when brakes are applied. If runout is severe enough, the pads can bounce on/off of the rotors during driving, even without applying the brakes. The resulting vibrations produce annoying brake squeal due to the harmonics generated as the pads bounce/chatter against the disc.
NOTE: Since runout stack-up can occur between the hub and rotor, frst matchmark one stud location on the rotor and its stud. Perform a runout check with a dial indicator. Then re-locate the rotor to the hub in the next clockwise position and measure again, etc. in order to obtain the optimum location of the rotor to the hub with the least amount of lateral runout. If further correction is needed, a tapered alignment shim may be installed to remove any remaining lateral runout. Lateral runout of the brake rotor can result in not only a vibrational issue, but can lead to premature brake pad wear as well. Corrective tapered shims are available to address this issue, potentially eliminating the need to re-machine the rotor. Shims offered by Nucap are a good example (213 SKUs available). Available in different bolt patterns and shim thickness to correct up to as much as 0.009 inch lateral runout, the shim is simply placed between the hub and rotor. Using a dial indicator, slowly rotate the rotor on the hub, noting (and marking) the low point of lateral runout. The shim is then installed with the thickest section aligned with the low point of measured runout (180 degrees from the high point of lateral runout). For example, if the rotor was measured with a high point lateral runout of 0.006 inch, the low point will be located 180 degrees from the high point. A taperedthickness shim with the thickest section of 0.024 inch on one side (the side with the “V” notch) and 0.027 inch on the opposite side is placed onto the hub prior to remounting the rotor. The 0.003 inch difference in shim taper makes the initial 0.006 inch runout disappear. The side of the shim that features the “V” notch is the thinnest side of the shim, making the thin/thick sides readily identifable.
TIRE RADIAL FORCE VARIATION In addition to dynamic balance of a tire/ wheel assembly, we need to consider tire radial force variation (RFV) when diagnosing tire-related vibrations that occur at varying speeds and conditions. Ideally, the

The Chassis the type of tire construction. Radial force vibration could potentially occur with any type of tire, regardless of its construction (radial, bias ply, etc.). In other words, a radial force variation may prove to be the cause of a vibration that won’t reveal itself during a static or dynamic balance job, or by checking the mounted tire for runout in an unloaded state. Radial force is determined by measuring loaded radial runout. According to Hunter Engineering Corp.’s research, on an average passenger car tire/wheel assembly, one thousandth of an inch (0.001 inch) of loaded radial runout is equivalent to approximately one pound of road force. For example, a measured 0.030 inch of loaded radial runout (about 30 pounds of road force) will cause the same amount of vibration as 1.5 ounces of wheel imbalance at 50 mph, which is fve times greater than the .30 ounce imbalance limit. Tire makers usually supply a red dot on the tire sidewall, which indicates the tire’s maximum RFV. When mounting the tire, this red dot should be aligned to a white dot on the wheel (if the wheel is so marked). The white dot on the wheel indicates the wheel rim’s minimum radial runout point (on a steel wheel, a dimple may be featured that indicates the wheel’s low point). When using alloy wheels that don’t feature a white dot, the tire’s red dot should be aligned with the valve stem, as
Circle 111 on Reader Service Card
this should be the minimum radial runout point. A yellow dot may be found on the tire sidewall which indicates the lightest point of the tire (in terms of weight from a balance consideration). If a yellow dot is found, this should be aligned to the wheel’s valve stem, which should be the wheel’s heavy spot in terms of balance. Even if dynamic wheel balance (from a standpoint of weight) is correct, misalignment of the red and white dots will likely result in a vibration complaint. On OEM tires and wheels, ALWAYS align the red tire dot and the white wheel dot (or valve hole, in the case of alloy wheels) when mounting. If the tire features a red dot and a yellow dot, the red dot is more critical and should be aligned with the wheel’s low point (dimple or valve stem). • Red dot on tire: Align to the wheel’s lowpoint dimple (steel wheel) or to the valve stem (alloy wheel); or to a white dot on the wheel if the wheel features a white dot. • Yellow dot on tire: Align to the wheel’s valve stem. • Both red and yellow dots on tire: The red dot takes precedence. Align the red dot to the wheel dimple or valve stem. When a customer complains of a “tire vibration,” although the root cause may simply involve a static imbalance, other

The Chassis factors may be at play, including a static radial runout of the wheel and/or tire, a suspension/chassis problem, or a dynamiconly runout condition, known as radial force variation of the tire. If static imbalance is the culprit, this is easily cured by balancing the tire/wheel assembly. If runout is the cause, this can be cured by replacing the faulty wheel or tire; or possibly by match-mounting the tire/wheel package. However, when that approach does not fx the problem, the technician must begin a diagnostic approach in order to locate the cause.
RADIAL RUNOUT

When a “mystery” vibration enters the shop, approach the problem in a systematic
manner to eliminate possible variables. Naturally, check the tire/wheel assembly for balance on your shop’s balancer. If dynamic balance is verifed, begin measuring for excessive runout. First check hub runout in order to identify or eliminate the hub as the possible root cause of the problem. With the wheel/tire removed from the vehicle, check the runout of the hub. This can be tricky because of clearance at the wheel studs, but can be accomplished with enough patience. If the wheel is hub-centric (where the wheel relies on hub centering at the wheel hub hole to the hub protrusion), you’ll want to check the runout of the hub itself, at the contact area for the wheel’s center hole. If the hub center protrudes far enough from

the wheel studs, mount the dial indicator so that the plunger contacts the hub surface. In some cases, it may be necessary to remove the wheel studs to gain access to the hub contact area. Pre-load the plunger slightly and zero the dial. Rotate the hub slowly, watching for runout on the gauge. If the wheel is lug-centric (as we mentioned earlier, where the wheel-to-hub centering relies on the location of the wheel fastener holes to the hub’s studs only), you can mount the dial indicator so that the plunger is about .040 inch away from the outer edge of the wheel stud pattern diameter. Using a feeler gauge, check for changes in the gap between the dial indicator plunger and the outer edge of the wheel studs as you slowly rotate the hub 360-degrees. Granted, this can be a timeconsuming and nit-picky job, but this will either recognize the wheel-to-hub mating as the culprit, or eliminate this variable from your diagnosis. NOTE: Do not use the outer edge of the brake rotor as your measurement point when trying to check hub runout. You must take this measurement at the centering area that the wheel uses, whether this is the hub (for hub-centric wheels) or the wheel studs (for lug-centric wheels).
HIGH TECH TIRE ANALYZER Here’s an interesting way to generate additional wheel alignment, tire and steering/suspension components. Tread Spec (see www.treadspec.com) offers a drive-over laser scanning system that reads tire tread and collects several hundred data points. The technician can refer to the data to talk to the customer about the measured tread wear in terms of tread depth and uneven wear, which can naturally lead to the need for tire replacement, wheel alignment, and steering and suspension components sales. While any experienced technician may be able to interpret tire wear visually (hey, you have excessive inside shoulder wear, so you’re likely running too much negative camber, etc.), this system provides documented data that substantiates the technician’s diagnostic opinion.

different systems are available, including a service bay system and a service drive system. In each case, the tires pass over laser scanners housed in low profle ramps. The bay system allows a technician to drive the front axle onto the scanner platform and stop, allowing a scan of the tires. A technician-operated bar code scanner is included that allows scanning the vehicle VIN for record keeping purposes. The service drive system can be located at the entrance of the bay area, where the customer drives over the ramps as the vehicle enters the service area. The basic difference between the two systems is that the technicianoperated drive-over system features two lasers, where the customer drive-over system features eight lasers to capture all four tires at the same time. Data that is collected by the system is sent to the manufacturer’s cloud-based collection point and is then available (in real time or after-the-fact time) on the shop’s desktop computer. While such a system may not be mandatory, it certainly can help to boost shop sales by increasing parts and service tickets, since the “high tech” data collected by the tire scan provides documented proof of tire tread condition, and immediately allows the technician to begin a discussion of tread wear and the potential causes and remedies. ●

ack in the day when electronic fuel injection and computers in vehicles were frst coming out, oxygen sensors were new. Technicians freaked out wondering how they worked and had to fgure out new ways to diagnose vehicles. Eventually, they got used to the pattern failures (i.e. oxygen sensors stuck lean, bad heater circuits, etc.) and understood how they worked: the richer the fuel mixture, the higher the voltage and the leaner the fuel mixture, the lower the voltage. Then, air/fuel sensors came out and also

Powerplant confused technicians worldwide. The sensors worked in the reverse fashion, and instead of switching between high and low voltages, they used a steady, unspecifed voltage. As recently as 2010, a young, ASE L1 with 12 years in the feld told me, “There is no way to properly diagnose air/fuel sensors.” However, as more time passes, technicians are getting increasingly familiar with diagnosing these sensors. Nonetheless, there are still some changes afoot that are worth tracking.
‘New-school’ oxygen sensors Many service techs thought that the days of having to learn anything about oxygen sensors were over. Think again. Chrysler
vehicles still exclusively use oxygen sensors, as opposed to air/fuel ratio sensors, to give the powertrain control module (PCM) feedback in order to calculate whether combustion is stoichiometric, or in plain English, if the exhaust is rich or lean. However, intent on not making the lives of technicians easy, vehicle manufacturers are beginning to employ oxygen sensors that read between voltages higher than 1V. In fact, the front and rear oxygen sensors on Chryslers for the last few years, including 2014, are 5V sensors. On an example using a 2008 Jeep Grand Cherokee 5.7L (see Figure 1), the oxygen sensors read between 2.6 and 3.4V when we use enhanced OBD II on an OTC Genisys. Why is the Bank 2 sensor stuck at 3.3V? We’ll see in a moment.
FIGURE 2 This Chrysler wiring diagram, courtesy of Mitchell 1 ProDemand, shows how the power/return wire runs through the variable capacitor to the sensor and exits as the signal wire to the PCM.

FIGURE 3 On this 2014 Dodge Charger 3.6L the front oxygen sensor works just like a traditional one, but the voltages refected in generic OBD II, between 0V to 1V are inaccurate.
Why is this? Instead of being a zirconium dioxide oxygen sensor, these 5V sensors use titanium dioxide. It is probable that this fact has skipped many technicians’ notice, simply because they do not look at Chrysler oxygen sensors very often. Chryslers do not like throwing system lean DTCs, even when they have massive vacuum leaks. The way titanium dioxide oxygen sensors on Chryslers work is that they receive 5V of power from the PCM from what is called an “O2 return” wire. The Bank 1 and Bank 2 sensors share the same O2 return wires and each individual sensor has a “signal wire” which in reality is the ground wire (refer to Figure 2 for a Chrysler wiring diagram, courtesy of Mitchell 1 ProDemand). This shows how the power/return wire runs through the variable capacitor internal to the sensor and exits as the signal wire to the PCM. The changes in oxygen in the exhaust
create a voltage drop in the sensor, which the signal/ground wire sends as a voltage to the PCM. The PCM then interprets these voltages to know what air/fuel mixture or catalytic effciency is. Just like on a standard oxygen sensor, these sensors “switch” up and down in an identical fashion. Instead of switching between 0V and 1V, Chrysler specifes that they switch between 2.5V and 3.4V. When using OEM Enhanced data on a scan tool, or a labscope, this is how it will appear. However, in generic OBD II the sensors simply read between 0V and 1V and work just like a classic oxygen sensor. As long as the technician uses generic OBD II to diagnose these sensors, he won’t even notice the difference. See Figure 3 for an example on a 2014 Dodge Charger 3.6L, where the front oxygen sensor worked just like a traditional one, but the voltages refected in generic OBD II, between 0V to 1V are inaccurate.

FIGURE 4 The rear oxygen sensor on the same vehicle has a steady voltage of around 685mV according to generic OBD II. We know this is inaccurate, but we know that on traditional oxygen sensors, a steady reading of such a voltage would refect high catalytic effciency. After going WOT, the voltage drops precipitously as the fuel mixture is leaned out during the throttle snap.
It is worth noting that the rear oxygen sensors on these newer Chryslers are also of the 5V variety, but they likewise work identically. In Figure 4, you’ll see that the rear oxygen sensor on the same vehicle had a steady voltage of around 685mV according to generic OBD II. We know this is inaccurate, but we know that on traditional oxygen sensors, a steady reading of such a voltage would refect high catalytic effciency. After going WOT, the voltage drops precipitously as the fuel mixture is leaned out during the throttle snap. (Figure 4a shows some new vehicles, such as the 2013 Ford Edge 3.5L.) After testing two different 2014 vehicles, both with the Chrysler 3.6L motor, we found that the update rate on the oxygen sensor was practically instant. The only time testing these sensors might be confusing is when using OEM enhanced data on the scan tool as opposed to generic OBD II.

sensors. While this may be important when looking at an air/fuel sensor on an older vehicle where it would be tough to know whether it is shifted lean or not without having the right specifcations, for these Chryslers it is not terribly important. The 0V to 1V scale works fne and is much more familiar to the average technician. Furthermore, newer vehicles now give the correct specifcation for the front air/fuel sensor in generic OBD II, or even better yet, give us the mA PID to go by, which is all one really needs. Being that this is the case, it is best to get into the habit of using generic OBD II when diagnosing all check engine light issues.

can compromise both sensors. Further, an exhaust leak on this bank can also conceivably throw these DTCs. However, in Figure 1 on page 32, the front oxygen sensor appears to be switching normally while the rear one is stuck at 3.3V. No exhaust leaks were found and as a quick down and front oxygen sensor working normally seems to exclude a common power issue. In order to quickly rule out the PCM, the oxygen sensor was removed to see if the PID went to 5V, which tells us that there is an open circuit. If the PID is correct, then it is the sensor giving the incorrect feedback, not the PCM misinterpreting it. Before going crazy looking for common power issues, especially when the front sensor works so normally, it is wise to replace the rear oxygen sensor. See Figure 5: Due to the connectors for the oxygen sensors, this vehicle was tested again after the exhaust cooled down a bit.

Air/fuel sensors and the mA PID The air/fuel sensor is the most common fuel-control sensor there is and it is probably the only fuel control sensor most technicians come across these days. Air/fuel sensors work off the principles of Lambda, covered in much detail in my recent article Lambda diagnostics: Solve those lean problems fast, which appeared in the May/June 2014 issue of Auto Service Professional. Here’s a recap: For all intents and purposes, if you have a Lambda of 1.0 you have a perfect running engine. If you go below 1, you begin running rich. If you go above 1, you run lean. Anything within 0.97 to 1.03 is normal, but if you go above these numbers and the vehicle has a code for fuel trim or a converter issue, it is worth taking a closer look. However, don’t be hyper sensitive. If the vehicle is running fne and has a Lambda 1.08 or 0.95, that could be “good enough.” Just remember how it works: above 1 is lean and below 1 is rich. Now, also remember that instead of the Lambda number 1, it is important to know the air fuel sensor’s voltage specifcation. Anything above that voltage specifcation is lean and below it is rich. One of the toughest things about air fuel sensors is that no one tells you what a known good voltage is. Without knowing what your PID should be, it is very diffcult to diagnose an air/fuel sensor. The following are known good voltages for air/fuel sensors compiled over the last few years: 3.3V (Toyota), 2.8V (Honda), 1.9V (Hyundai), 2.44V (Subaru), 1.47V (Nissan), 1.00 Lambda (all European manufacturers). Companies are not always forthcoming with this information, so you will have to compare voltages with known good vehicles. Occasionally, service information will contain such data. More importantly, remember the number zero in place of 1 Lambda. This is perfect air/fuel mixture when using the mA Circle 119 on Reader Service Card

specifcation which is now available on almost every newer and new vehicle. For every single air/fuel sensor to date a perfect air/fuel mixture will measure 0 mA. Each tenth of a milliamp above zero is about a tenth of Lambda in the lean direction (i.e. 0.1 mA equals 1.1 Lambda, 0.5 mA equal 1.5 Lambda, 1.0 mA equals 2.0 Lambda, etc) and each fraction of a milliamp below zero is a fraction rich (i.e. -0.1 mA equals 0.9 Lambda, -0.15 mA equals 0.85 Lambda, and etc.) Hence, this works fundamentally the same as emissions analysis. In the old days, in order to test for mA the technician had to connect his meter in series with the air/fuel sensor in amps mode. Now, almost all newer vehicles contain a mA specifcation in generic OBD II. This makes diagnosing air/fuel ratio sensors a breeze, as long as the principles of Lambda
are understood and the means to test the sensor, such as a bottle of propane, are available. See Figure 6: The air/fuel sensor in a 2014 Kia Soul didn’t reveal much of anything when graphed. However, it reached 2.6 mA when in wide-open-throttle, which showed a movement in the lean direction, before settling at an ideal lambda of 0 mA. Figure 7 shows an example of a 2013 Ford Edge perfect Lambda air/fuel sensor reading of -0.016 mA, which is good for a 1.004 Lambda. Refer to Figure 8, which shows a perfect Lambda as displayed on an ANSED emissions analyzer.

synthetic engine oil. And curiosity is again piquing in many car owners’ minds since so many makes and models now require synthetic oil. A chemist at Mobil isolated the frst polyalphaolefn (PAO) molecule while researching another project. It became nothing but an interesting lab book note back in 1949. In the 1970s, the OPEC oil embargo prompted motorists and oil companies to fnd ways to conserve resources. That’s when Mobil 15W-30 was introduced, reportedly providing up to a 5% increase in fuel economy. What is the fundamental difference between
conventional and synthetic motor oils? Conventional oils, refned from crude contain a plethora of molecules. This variety makes the oil a good lubricant, for the most part. However, this mixture of molecules all has different boiling points and some break down more readily than others. The remaining molecules may cause the oil to become too thick at low temperatures and too thin at higher temperatures. The oil essentially wears out. Synthetics, on the other hand, have just a few molecules — just the best ones for lubrication. They resist high temperature breakdown and keep their lubrication ability.

In this example (using a 2001 PT Cruiser), I demounted the caliper and removed the inboard pad. I inserted the load cell into the narrow opening at the top of the caliper body and then rotated the load cell so that the back of the load cell block contacts the piston.
62 | July/August 2014
Tool Review INDICATION Pressure readings are low but even. POSSIBLE CAUSE Both rear drum brakes are badly out of adjustment, the master cylinder is bad, the power booster is bad, or the ABS is in need of repair. The load cell/gauge units measure about 10.5 inches in length, an ideal length for any disc brake application in terms of handling, access and readability. The pressure range is 0 psi to 5,000 psi (0-350 BAR).
Each gauge is ftted with a protective rubber surround cushion shield, which is a nice touch.
Sticking calipers and imploded hoses Calipers that stick or fexible brake hoses that “implode� (collapse) can easily contribute to uneven pad wear. If the piston(s) in the caliper cannot move freely, sticking in various positions or in the extended position will place excess pressure on

Tool Review
With the caliper remounted, the gauge hose hangs out of the caliper opening.
inboard, outboard or both pads. Degraded brake hoses that tend to implode when the brake pedal is released can cause a restriction in the hose, preventing full release of the pads from the rotor disc. If you suspect sticking pistons in a caliper, inspect closely for worn, degraded or burnt piston seals. None of us have X-ray vision, so it’s diffcult to see what’s going on inside the caliper piston bores. If a sticking caliper is suspected, remove the caliper, place it in a bench vise and insert a hefty shop rag inside the pad cavity and carefully apply shop air to the bleeder to push the piston(s) out. You may discover galled or rusty pistons and damaged seals. Never assume that what you can’t see can’t be the problem. Hose implosion may be temporary, gradually releasing pressure after the brake pedal has been released. This will cause residual pressure in the caliper, preventing the pads from fully releasing from the disc.
The result is obvious: If there is a pressure difference (wheel to wheel on the same axle), of if pressure does not release fully causing pad drag, premature pad wear is inevitable.
Our in-shop experience For our test, we chose a 2001 PT Cruiser. The front brake pads are captive in the caliper (can’t be removed from the top with the caliper mounted), so temporary removal of the caliper was necessary by simply removing the two 8 mm caliper-to-caliper bracket bolts. With the inboard pad removed from the caliper bracket, the gauge load cell was positioned against the caliper piston (black blank side contacting the piston, with round pressure pad facing the rotor). Due to very limited access for the gauge load cell and gauge hose (the opening in the top of the caliper is very narrow and 90 degrees to the rotor), I slipped the load cell through the caliper top opening, then
64 | July/August 2014
Tool Review rotated the load cell 90 degrees. I then resecured the caliper to the caliper bracket. I did this to both front brake locations. The rotors were secured with a couple of lug nuts in order to stabilize the rotor and keep it in line with the calipers. As an assistant pressed on the brake pedal, both gauges read 980 lbs. under very moderate braking pressure and climbed to 3,500 lbs. under heavy braking pressure. Both gauges held steady as pressure was maintained. Upon release of the brake pedal, the right side gauge black needle dropped back to zero very quickly, while the left side dropped notably slower. This led us to directly consider a sticking piston or an imploded hose issue on the left front brake (turned out to be an imploded brake hose). Basically, these load cell tools are research lab-grade units that are designed for realworld in-shop use. Measuring load pressure
at each wheel is easy and provides solid diagnostic information that can lead you to the source of a problem where the initial concern was one of inadequate braking, spongy pedal, uneven brake wear, brakeinduced pull and more. Being able to measure and verify clamping pressure at each wheel on the same axle is a real time-saver, leading you to a quicker and more accurate/intelligent diagnosis of the brake system. I can enthusiastically recommend this tool. It’s a great design and quickly earned an honored spot in my shop. It’s a keeper. ● MANUFACTURER INFORMATION IPA (Innovative Products of America) 234 Tinker St. Woodstock, NY 12498 845-679-4500 www.ipatools.com
