Most, if not all of us, have seen the dreaded “Check Engine” or “Service Engine Soon” message illuminate on the dash. This is called a “Malfunction Indicator Light” (MIL). They first appeared in vehicles in the early 1980s. The automotive industry started adding computers to
help control exhaust emissions and to improve fuel economy. Over the years, more and more computer systems have been added, making our vehicles much more sophisticated and complex. They control everything from creature comforts to parking the car for us. So why did your light come on? The main computer, sometimes called the Powertrain Control Module (PCM), monitors and controls the way your engine, transmission, and emissions system operate. The PCM monitors a multitude of sensors for information on things like how far you have pushed the gas pedal, to the amount of air that is entering the engine. The PCM also controls many electromechanical devices based on the information these sensors provide.
When the PCM detects a sensor that is out of its normal operating range, or one of the electro-mechanical devices malfunctioning, the PCM then sets and stores an “Error Code” and turns on the MIL. What does it mean? There are a multitude of possible “Error Codes” the PCM can set, it seems almost as many as there are stars in the sky. Some codes are for minor issues, like a loose gas cap, but an Error Code can also signal major issues that can cause engine or exhaust system damage. A flashing MIL indicates a more immediate concern, like an engine misfire happening at that moment. How do I turn it off? You will need a Code Reader or Scanner to access the PCM to read the stored codes. There are a variety of
cheap code readers for the DIY's, and much more capable scanners for the professional diagnostic technicians. Most automotive parts stores will read the error codes for free and clear them for you. Should the error code return, I urge you to take your vehicle to a professional automotive diagnostic technician. Please understand that if your PCM set a code, for example, an Oxygen Sensor code, that does not necessarily mean the Oxygen Sensor is bad, only that it has detected too much, or too little oxygen in the exhaust flow. I hope that this explanation of why the Check Engine Light illuminates is helpful. Please feel free to contact me at sam@absoluteautomotive.net if you have any questions or I can help in any way.

Create a Home Workout Space by Sally Whitaker
Choosing to work on your fitness at home has many advantages, including: less time away from home/family, no gym memberships or class fees, convenience, and the element of intimidation or self-consciousness is removed. It also presents some challenges, like staying motivated to put in the time. Having an area devoted just to your workouts is important and does not require much space. A little planning goes a long way to build your home gym. Location Whether you have an entire room to devote to fitness equipment or just one corner, setting up a specific spot will help you to stay on track. Just like walking into the kitchen tends to lead us to grabbing a snack or drink, walking into your workout space will get you in the mindset to move. If you have a space large enough to
hold a plank or do a jumping jack, you have plenty of room. Equipment Yoga Mat - Great for yoga, Pilates, ab work, or more traction for standing and jumping. Dumbbells - Start with just one or two pairs, a weight that is manageable for 8-15 reps of an exercise, and a weight that is just a bit heavy. Check for sales to continue to add to your collection. Jump Rope - No treadmill, no problem. A jump rope will provide plenty of cardio and is great for interval training. Resistance Bands - A couple resistance options for strengthening and stretching will enhance your workouts by providing many options without taking up a lot of space. The above options are more than enough to get started. As you progress, you will be able to add more detailed
Storage If space is limited, proper storage is imperative. A bookshelf, basket, or even a storage tote are great options. Treat your space just like you would a gym, and wipe down your equipment, roll up mats and bands, and make sure everything has a spot to be stored. This will help you to begin each workout with a clean space and in the proper mindset. Accessories What helps you when it comes to your workouts? Will you want music? A mirror to check form? Bright lights or a small lamp? Having what you need close at hand will keep you from having to break from your workout to go get it. Plan Ahead Creating a workout routine is important. There are many resources online and in print that will provide specific plans. Additionally, many
You should consult your physician or other health care professional before starting this or any other fitness program to determine if it is right for your needs. Do not start this fitness program if your physician or health care provider advises against it. If you experience faintness, dizziness, pain or shortness of breath at any time while exercising you should stop immediately.
