What to do if the check engine light goes on 

Picture this, you're driving along in your car or truck and suddenly a yellow light illuminates your dash telling you to "check or service your engine."

If you're like most car owners, you have little idea about what that light is trying to tell you, or exactly how you should react. It doesn't mean you have to pull over to the side of the road and call a tow truck. However, it does mean you should get your vehicle checked out as soon as possible. If you ignore the warning you could end up damaging expensive auto components. It also can be a sign that your car is getting poor fuel economy and emitting higher levels of pollutants.

At DeWildt our auto service professionals are equipped with the latest in diagnostic equipment and are able to locate the root of the problem and repair it in a fast and cost effective manner.

What the check engine light means

The check engine light is part of your car's onboard diagnostics (OBD) system. Since the 1980s, computers increasingly have controlled and monitored vehicle performance, regulating such variables as engine speed (RPM), fuel mixture, and ignition timing. In some vehicles, the computer also tells the automatic transmission when to shift.

When it finds a problem in the electronic-control system that it can't correct, the computer turns on a check engine light indicator.

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. The code can be read with an electronic scan tool or a diagnostic computer, both are standard equipment at DeWildt Chrysler.
