EDITOR’SNOTES Looking for a New Job or Employee? Narrow Your Search at Our New Automotive Job Site re you a shop owner in need of qualified employees? In today’s competitive business climate, it’s imperative that you find eager, qualified candidates to ensure your company’s success. Or are you a technician or parts distribution professional seeking a job that better matches your skill set? The demand for skilled workers in the automotive repair industry is higher than ever and continues to grow each year. Based on a study by U.S. News & World Report, automotive technicians made the list for the Top 100 Best Jobs in 2013. The top 100 jobs were chosen according to their ability to meet three important factors: the number of available job openings, the opportunity for advancement within the field and the ability for workers to meet their financial obligations. To best serve our readership, Babcox Media has recently launched a new job board site — AutoProJobs.com — with a team backing it up that’s here to help applicants stand out from the crowd, and connect employers to the qualified automotive professionals they’re looking to hire. Applicants can post their resume online for prospective employers to find, and stay up-to-date on the latest industry happenings through the newsletter and blog. There, you’ll find information on improving your job search, ASE test-taking tips and advice, and more. Not only will your job be posted on an industry exclusive job board, but on an array of Babcox Media e-newsletters and websites — including Tool Connect and TechShopMag.com. Our team will make sure your posting is seen by the right people in the industry. And part of the AutoProJobs team may be coming to a shop near you — maybe even your shop! The AutoProJobs team — Libby Melhus and Hallie Brown, under the direction of sales manager Karen Kaim — wanted to get actively involved in the industry.

“Along with providing the latest job openings and resources for the job hunt, we decided to start a blog chronicling our experiences as we immerse ourselves in shop culture and get to know day-to-day life in a shop,” Libby said. “We’re planning on highlighting different shops around the Midwest and learning new things along the way.” “Anyone can try and say they know about a career,” Hallie said. “But we don’t want to just say we know what it’s like to be a technician in the automotive industry –– we want to actually experience it. Now, I’m not saying that visiting a shop for a couple hours will make us professionals, but it will give us the experience to talk about the dedication employers and employees put into their work. And it goes even farther than that. We’ll be able to hear firsthand what’s going on in the car care industry –– good or bad –– and convey that information to you.” So stay tuned for some interesting (and probably amusing) posts from the team. Be sure to connect on Facebook and Twitter: w w w. f a c e b o o k . c o m / A u t o P r o J o b s and twitter.com/Auto_Pro_Jobs for the latest job postings and updates. TS

ulling a P0135 Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) code means you’re dealing with a possible oxygen sensor heater element and or associated components in this circuit. This article will attempt to provide a game plan for diagnosing a vehicle with this code. I’ve found through my research that all of the car manufacturers appear to have similar logic on how these systems may work, but I always start my process by looking to see if any feed or ground issues may exist in the circuit. A quick review of the schematic for this system shows a feed supply, A/F fuse, A/F relay, A/F sensor heater and ECM. This month’s diagnostic journey begins with a Toyota product. (See sidebar on page 8 for information on a training video that offers a good perspective into the operation of these Toyota systems.) Our subject vehicle is a 2003 Toyota Highlander 3.0L.

A Techstream snapshot was performed and Figure 1 notes the activity on A/F B2S1; there was no activity noted on A/F B1S1. The tool also indicated that there was a P0135 stored in the controller’s memory. I decided that I would first review the activity on A/F B2S1, as this would provide a base for knowngood. Figures 2 and 3 on page 10 from the Pico lab scope show the voltage available at the feed side of the

The voltage is to be checked on the feed side and the control side of the oxygen sensor heater circuit to get the full electrical picture. Figure 2 shows the feed side voltage as well as the switching current in the heater circuit. The voltage on the other side of the heater circuit was checked and found to be switching as well. This denoted known-good activity. Figure 2 indicates that there is a good feed, relay and wiring up to the heater circuit in one visual. We will now take a look at our suspect sensor A/F

12-17 Scopes Article_Products 2/11/14 10:21 AM Page 12

BUYING A SCOPE

A scope is by definition just a meter that can plot the information on a graph. But, today’s scopes are so much more. Faster processors, better software and new sensors are allowing scopes to capture more detailed patterns and they can help you to interpret them. If you’re in the market for a scope, it can be confusing. A full-feature scope with all the accessories can cost more than a scan tool. To get the most bang for your diagnostic dollar, here are six items you should look for when buying a new scope.

1. Automotive Scopes Only

2. Look at the Manual Online

This tip is for the newbies. It’s easy to find a singlechannel scope for less than $200. These are not designed for automotive technicians. Cheap generic scopes have very low sample rates and can’t buffer enough information for faster waveforms like serial data bus circuits. Also, the refresh rate of some cheap scopes can leave you looking at a blank screen when there actually is a lot of activity. Some automotive scopes have a “glitch snare” function that can capture waveforms to expose abnormal signal patterns.

Many scope manufacturers have the manuals for their scopes available online in PDF format. This is very valuable for evaluating if a scope will meet your needs. If a manual is not good, chances are the scope will not be good.

3. Automated Tests Some scopes have built-in testing modes for primary ignition circuits, cylinder balance and alternator signal patterns. These special modes can guide you through the correct connection, leads and what procedures to perform on the vehicle. These can be a real time-saver and help you to perform a more accurate diagnosis.

4. Bundles Many dedicated scan tools offer a scope as an option. Many of these

12-17 Scopes Article_Products 2/11/14 10:21 AM Page 14

BUYING A SCOPE simply plug into the scan tool or slide into a slot as a module. Some new scan tools interface with the scope module via Bluetooth. Ask your scan tool provider what they offer for a companion scope.

A computer connection can also be used to update the firmware of the scope. This can increase the functionality of the tool during its entire life.

6. Online Support 5. Computer Connection One of the most valuable features on diagnostic tools is the capturing and sharing of information. Being able to transfer waveforms from the tool to a computer allows you to build a waveform library and share online to analyze the information.

Before you buy a scope, visit the manufacturer’s website to see what support they offer for users. Some manufacturers offer reference libraries of waveforms and user forums to interact with other users. Using these features can help you get the most of your new scope.

10 Scope Accessories You Can’t Live Without

If you’re buying a new scope or upgrading one you already own, here are 10 accessories that can make you more productive.

1. Pressure Transducers

4. Connector Adapters

A scope can be used to diagnosis mechanical systems if you have the right accessories. A pressure transducer turns pressure changes in air and fluids into signals that can be displayed on a scope. With a pressure transducer connected to the dipstick tube, you can perform a leak-down check without pulling a single spark plug. They can also be used on cooling, transmission and exhaust systems. Kits will vary in price depending on the pressure range of the transducer and the adapters included in the set.

On some circuits, sticking a pin into the insulation can lead to corrosion problems like in the case of wheel speed sensor circuits. Connector adapters can allow you to make your measurements without damaging the insulation or pins in the connector.

2. Breakout Boxes Nothing is worse than probing an OBD II DLC or small connector only to push the wire out the back of the connector. One of the best investments you can make is the purchase of breakout boxes. The most popular application for breakout boxes is the OBD II connector. This tool can allow you to leave a scan tool connected while still having access the pins of the OBD II connector. This can be very helpful when diagnosing serial data bus problems.

14 February/March 2014 | TechShop

5. Current Clamps If you need to measure the amount of current in a circuit, you need a current clamp. Current clamps can measure the draw of a module to the amount of current needed for a starter. Be sure to select the right range and features for your diagnostic needs.

6. Test Leads You can skimp on the scope, but never skimp on the test leads. Better-quality leads have better shielding to prevent random signals from leaking into the wires. Higher-quality leads use higher-quality materials that are temperature resistant and are more flexible. They don’t tangle easily and you won’t fight them.

12-17 Scopes Article_Products 2/11/14 10:21 AM Page 16

BUYING A SCOPE 7. Gators and Probes Your test leads are only as good as what is connected at the other end. High-quality alligator clips can help you by establishing a stable ground to test circuits. Back probe pins can be found in many sizes. These pins can be used to pierce wires and the insulation in connectors to reach the terminal. When buying pin probes, the more money you spend, the smaller the probe.

8. Secondary Ignition Signal Probes/Paddles These inductive sensors can be placed on ignition coils to capture the secondary ignition waveform. They do not require any back-probing or removal of the coil. Some of the probes and paddles can be used to monitor fuel injector cycle times.

9. Case

Weight Gauge Offers Increased Accuracy Mohawk’s 4” diameter weight gauge accurately weighs vehicles within 3% of total vehicle weight. Available for all Mohawk twopost lifts as a diagnostic tool, the weight gauge will assist your shop in selling better-quality brake pads, better tires or heavier shocks by giving techs the opportunity to show customers how much their vehicles really weigh. A safety feature of the weight gauge is the visual verification that the lift has been lowered onto the mechanical safety locks (as the gauge will then read 0 lbs.), and the diagnostic tool for a customer that may complain about poor driveability or poor mileage if they don’t realize the vehicle is carrying extra weight. Mohawk Lifts Circle #64 for more information

Any amount of money spent on a protective case for your scope will be recouped when you try to sell your scope. A quality case will protect your scope from chemicals and the occasional drop.

10. Time & Training The best accessories you can purchase for your scope are time and training. Great scope technicians are not born, they are made. During shop downtime, pull out your scope and start playing with the menus and measure a few vehicles to build a waveform library. Take time with the manual and use any online support. TS

TOOLING UP

often say that before getting started in the bay, you must prepare your most important tool for the diagnostic job — your brain! However, for this article, I’ll discuss the importance of other types of tools that we as technicians use to aid in our diagnostic process. Oftentimes, I am told by fellow techs and students how impressive my collection of tools appears to be. See Photo 1. I believe that most techs have a tool fetish and, sadly, I am not exempt from this condition. What is most important, however, is actually using the tools that one purchases, whether they are basic hand tools, special service tools, scan tools, lab scopes, gas analyzers or whatever else that might be collected in that tool chest. That 3/8 ratchet that you use every day has easily paid for itself millions of times over, but what about the lab scope in your bottom toolbox drawer? Quality tools set us back a great deal of money and if we don’t use them often, we are merely collecting tools instead of using them to make us money! We have all heard about that guy on Craigslist who retires and tries to sell his lifelong tool collection totaling more than $100,000 for less than 20% of what he paid for it. The sad part is I don’t even think that most people get anywhere near as much as their already discounted price. I have personally purchased many tools from people at deep discounted prices and, yes, I too have sold some tools for prices far below what I paid for them. The best solution when buying tools is to only buy the ones that you know you will use to make money! After you purchase these tools, forget about ever selling them because you’ll take a loss. I would rather give a tool to a promising young technician to help them out than sell it for pennies on the dollar. We as technicians are bombarded with new tools promising to make our jobs easier and make us money daily. Some do, and some simply fall short. The secret isn’t owning every fancy tool that comes out, but rather it’s knowing our tooling needs and

then developing an intimate relationship with that tool. For the sake of this article, I counted how many 3/8 ratchets I currently own. I own 12 different 3/8 ratchets of various shapes and sizes. I, like you, have my personal favorite of the bunch, which I use daily! I know everything there is to know about this tool. I know its capabilities and its limitations. I can feel when there is something wrong with it, I have developed new uses for it such as propping up the intake

plenum when I’m changing the rear coil packs on many of the front-wheel-drive vehicles, and I just know this tool as well as I know my own right hand. It’s very important that we develop the same relationship with our more expensive diagnostic tools such as scan tools, scopes, volt meters, smoke machines, gas analyzers, etc. Just owning a lab scope, for example, won’t make you money. If you only use it a couple of times a year, you will never become proficient at using it, you may get a poor

waveform and not realize that it’s a result of something you’re doing wrong, or that the tool isn’t capable of displaying the signal you’re trying to view. Most of the articles that you read with instructors using their scopes to view engine timing correlations, vacuum waveforms, pressure transducing testing and other such items are a result of them having achieved an intimate relationship with that tool. They take their understanding of how a vehicle is designed to function, they know the limitations of what their tool can do, and finally they recognize a need for a particular test that can make our jobs easier to diagnose various problems found on a car. You can trust me when I tell you that there is absolutely no way they, or anyone else, can successfully use these newer testing procedures without having a thorough knowledge and understanding of both their tool and an understanding of how a vehicle is supposed to function. This takes years of practice and learning to accomplish. The benefits of taking the time to learn your tools and to learn as much as possible about the vehicles you work on are amazing! You will be able to not only diagnose vehicles quickly and correctly, but the process will be easier! All of this will make you more profit, which you can then use to buy more tools…

TOOLING UP

TIP:

It’s important to note that the way this vehicle has only one cat sensor, the problem could actually be either of the two pre cats or the final cat. In other words, it could be anything that may affect the catalyst sensor’s reading!

Let’s take a look at three examples:

Example 1: Weird/Tough Driveability Case Study: I had a 6.0L GM product come into my shop with a random misfire code stored in the PCM’s memory. I looked at the misfire history counters and noticed that all the cylinders on the left side of the engine had high misfire counts stored. After smoke-testing the engine, I noticed the intake gasket Circle #19 for Reader Service TechShopMag.com

was leaking, and upon removal of the intake I saw a high amount of carbon buildup inside the intake runners and on the injector tips themselves. I decided to flow-test the injectors while the manifold was off — the results were mind blowing! Photo 2 shows the left-side intake runners. Photo 3 shows the injector flow test results on a flow bench. Without having the ability to see the injector flow, I most likely would have still had the random

misfire codes stored. These injectors were way out of balance compared to the other side of the engine. After a good sonic cleaning they all flowed equal values and the vehicle was repaired! It’s important to note that I also performed an on-car cleaning to clean valves and upper engine components. This was a good example of having a specialty tool that although I didn’t need to repair this vehicle, having it did make my job easier!

Example 2: 2004 Ford F-150 5.4L; DTCs: P0171 and P0174 This vehicle came in to me with a rough idle and

stalling complaint associated with the above codes being set in the PCM. Before going crazy, I looked at the current fuel trim values as well as the freeze-frame data to verify a hard code condition was present. I quickly saw that the long-term fuel trim values were compensating for a lean condition. See Photo 4. We have a value of positive 12 on bank 1 and positive 16 on bank 2. On the factory side of OBD for Ford, the scale is engineered to go from 0 to 25% only! This is starting to make me think that we have to have a severe vacuum leak and possibly a contaminated MAF sensor. See Photo 5. Now, I finally get out of the car and open the hood. I

attach my scope lead to the MAF to perform a wide open throttle snap test. If the wire is clean, I would expect the voltage to climb quickly in 100 ms or less and reach a voltage of higher than 3.5 volts. You can see from the before and after cleaning results in Photo 6 that the MAF was indeed contaminated. Now, I still have that vacuum leak to find, so I always disconnect the power brake booster hose to attach my smoke machine. After a short time of inducing smoke into the intake system, I find the front corner of the intake is leaking and will need a new gasket. See Photo 7 on page 22. After a new gasket was installed and the computer was reset the fuel trim values returned to normal and

Example 3: 2003 Ford E-250 5.4L; DTC: P0420 Our last example is one of a P0420 cat code. When you’re confronted with one of these codes it’s important to accurately diagnose whether you need a converter or a sensor if you rule out the PCM and wiring as a potential problem. I started by pulling the codes. See Photo 8. As a first step when dealing with this code, one must determine if the fuel trims are out of synch. If your fuel system is compensating for a problem or if you have a misfire present, you must repair those areas first! I’m basically seeing in Photo 9 that the short- and, more impor-

tantly, long-term fuel trims are reading fairly normal so I can safely assume that my fuel mixture is operating correctly. At this point I plan to view the oxygen sensor’s data and see how they respond. I’m expecting to see a biased reading on 02B1S2, so once I do, I will try to manually change it by adding propane to a vacuum hose to help determine if the sensor is stuck or not. I can see in Photo 10 that both pre-cat sensors are switching as I would expect to see them do. They are switching fast and their voltage amplitudes are switching nicely, however, the cat sensor is stuck below 5 millivolts! When I introduce propane, I can get the catalyst sensor to rise ever so slightly up to about 80 mV. I decide it’s time to lift this vehicle

Photo 7

Photo 9

to closely inspect what I’m dealing with. I’m a little confused because I would’ve expected the cat sensor to rise higher with the added propane or not to have changed at all. Once the vehicle is raised, I see how this vehicle has its catalytic converters laid out. See Photo 11. This vehicle has a total of three converters on it. Bank 1 pre-cat is on the passenger side, Bank 2 precat is on the driver’s side and then after the Y-pipe, there’s the final converter. It’s important to note that the catalyst sensor is located behind the final converter on this vehicle. Each individual pre-cat has no sensor directly after it. While I could personally hear no exhaust leak coming from this vehicle while driving, I’m still curious about the readings I obtained Circle #22 for Reader Service

At idle, the catalyst sensor actually had a reading of about 100 mV, which quickly dropped as I accelerated the engine to a higher rpm of 2,500. Could I possibly have an exhaust leak somewhere?

ALI partnered with dealer services provider KPA to adapt material from the popular Lifting It Right DVD into an interactive, Web-based format. “With health and safety officials increasing their focus on vehicle service providers throughout North America, it is crucial that members of the service and repair industry take ownership of safety issues and embrace a proactive approach to accident prevention,” said R.W. “Bob” O’Gorman, ALI president. “Safety materials developed by ALI, such as this training program, allow employers to take a leadership role in service bay safety instead of simply reacting to penalty-based enforcement programs.” The training program costs $29 per trainee. Once registered, the user can take up to 90 days to successfully complete the course. If the participant fails the question-and-answer portion on the first try, he or she may study and review the course as needed before re-taking the online test a second time within the allotted 90 days. Upon completion of the program, each participant will receive a copy of ALI’s Automotive Lift Safety Tips card and the Lifting It Right safety manual via mail.

Compressor Range Extended to 50 Horsepower

Pure UV Flashlight Easily Spots All A/C and Fluid Leaks

Atlas Copco Compressors has extended the GA VSD+ range of oil-injected rotary screw compressors through 50 hp (37 kW). The GA VSD+ range reduces energy consumption by up to 50% and increases free air delivery by up to 13%, compared to a traditional load/unload compressor of the same type. Integrated with the Elektronikon controller, the cycle prevents condensation in compression oil, even in extremely low load conditions. The motor drivetrain is completely enclosed, resulting in a NEMA 4 rating for protection against dust, debris and water and the single closed oil-circuit cools the motor and lubricates the element and bearings, resulting in a very reliable and compact compressor that is also extremely quiet.

The Tracerline OPTI-LUX 365 (P/N TP-8691) is a powerful LED leak detection flashlight that provides pure UV light for optimal fluorescent dye response. Itâ&#x20AC;&#x2122;s ideal for all automotive A/C and fluid system applications. The OPTI-LUX 365 produces a brilliant glow that makes all leaks easier to find, while slashing valuable diagnostic time. The powerful flashlight brightly fluoresces both green and yellow dyes. It even pinpoints high-mileage, dirty diesel engine oil leaks. Compact and lightweight, the flashlight has an inspection range of up to 25â&#x20AC;&#x2122;. Powered by one rechargeable lithium-ion battery (extra battery included in kit), it provides four hours of continuous inspection between charges.
