What To Do When The Check Engine Light Comes On

Check Engine Light On? What To Do

Newer vehicles have as many as twelve networked computers and over five miles of wiring. In fact, for the last decade or so automotive computers have been controlling about 85 percent of your vehicle"e;s functions.

Vehicles have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do Oak Motors car owners know when there is a problem?

It’s simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.

It can be pretty disturbing for motorists when the Check Engine light comes on. If you wonder just how urgent it is, generally speaking it is not critical like a temperature or oil pressure light. When one of those lights comes on it means STOP NOW! However, if your Check Engine light flashes on and off it is more urgent and you need to get it checked as soon as possible to prevent damage to your vehicle.

If your Check Engine light turns on, you should schedule a visit to one of our Service departments in Indianapolis or Anderson to determine why the light came on. Your friendly Oak Motors service specialist has special diagnostic equipment that will retrieve the trouble code stored in the onboard computer and help determine what is wrong. From there, we can service it and get you back on the road!
