Check Engine Light Diagnosis

Why Check Engine Lights Turn On

Your Chevrolet is full of sensors that monitor various aspects of your car’s performance. Many of these sensors reside in your car’s fuel system, which includes everything in between your exhaust pipe and your fuel tank. When a sensor takes an abnormal reading, it generates a code that specifies the abnormal reading and where it came from, then it sends that code to the computer. The computer logs the code and then turns on the check engine light so that you can quickly address the abnormal reading and its cause in your Chevrolet.
