Visit Perez Auto For A Check Engine Light Diagnostics

One of the more disconcerting things that may happen while driving around Phoenix is when you suddenly discover a light illuminating on your dash. The “Check Engine Light”, and like most car owners, you’re not really sure what that light means, besides the fact that there may be some issues with your vehicle. Call it the one of the most misunderstood indicator on your dashboard, the “check engine light” can mean a variety of issues, from a loose gas cap to some seriously issues with your engine.

It doesn’t mean you have to suddenly pull over and call a tow truck. Although, it does mean you should get the car checked out as soon as possible. Ignoring any warning from your vehicle may end up damaging some expensive components. It also could be a simple sign that your car isn’t getting the best fuel economy and or emitting higher levels of pollutants.

What is The “Check Engine Light”

The “check engine light” is part of your car’s onboard diagnostics AKA the (OBD) system. Since the 1980s, computers increasingly have controlled and monitored your vehicle performance. Such as regulating variables as engine speed (RPM), ignition timing, fuel mixture and in some cars, the computer also tells automatic transmissions when to shift.

When it finds a problem in the electronic-control system that it can’t correct, the computer turns on a yellow warning indicator that’s labeled “check engine,” “service engine soon” or “check powertrain.” Or the light may be nothing more than a picture of an engine, known as the International :Check Engine” Symbol. In addition to turning on the light, the computer stores a “trouble code” in its memory that identifies the source of the problem, such as a malfunctioning sensor or a misfiring engine. If you bring your vehicle in to Perez Auto Repair we can read the code with an electronic scan tool or our diagnostic computer.

If your check-engine light comes on, here are some tips on what to do:

Look for a serious problem that requires immediate attention. Check your dashboard gauges and lights for indications of low oil pressure or overheating. These conditions mean you should pull over and shut off the engine as soon as you can find a safe place to do so. On some cars, a yellow “check engine” means investigate the problem, while a red “check engine” can mean stop as soon as it’s safe to pull over.

One of the first and most simple first steps is try tightening your gas cap. This often solves the problem. Keep in mind that it may take several trips before the light resets. If the light continues to stay on stop into Perez Auto Repair and we can reset it for you. Some vehicles have a separate indicator that warns of a loose gas cap before the condition sets off the “check engine” light.

If your “check engine” light is blinking or you notice any serious performance problems, such as a loss of power, reduce your speed and try to reduce the load on the engine. For example, it would be a good idea to stop towing a trailer. Have the car checked as soon as possible to prevent expensive damage.

What if I Need a State Emission’s Test?

In a late-model car, an illuminated “check engine” light probably is a sure sign your car will fail the test, even if the problem was nothing more than a loose gas cap.
