Why is Your Check Engine Light On?
The Check Engine Light strikes fear into the hearts of some people and is totally ignored by just as many. Why is it on? First, if your Check Engine Light is flashing, that means that something is wrong that could cause severe damage to the catalytic converter or other components. Bring your car to us right away!
If the light is glowing steadily, you should keep an eye on it for a day or two. If the light doesn't go off, schedule an appointment with us to get it checked out.
Most of your vehicle engine functions are controlled by a computer, not surprisingly, called an engine control computer. The computer is able to adjust many engine parameters for environmental conditions, engine conditions, and even the way you drive.
In order to make these adjustments, the computer relies on a network of sensors to provide data. The computer knows the proper operating range for each sensor. When a sensor reading is out of range, the computer runs some tests and may turn on the Check Engine Light. The computer will also try to make adjustments to compensate for some readings. If it can do so, it'll then turn off the Check Engine Light. If the problem can't be resolved then, the light will remain on and you should get your vehicle checked at my shop.
One of my technicians will plug a scanner into the on-board diagnostic port and read the trouble code stored in the computer. The trouble code will give us a starting place as we diagnose the cause of the problem.
