Ron :

Hello,

The service engine light comes on when the PCM (computer) sees a system fault and when this hapens the PCM will set and store a fault code and or codes, to know what has failed you will need to have the system scanned and the code and or codes retrived. Most part stors can do the scan for you at no charge. Once you have the code, we can direct you in the correct repair.
