    Is your check engine light ON? Try to diagnose your vehicle with a scan tool to determine what the stored trouble code in your vehicle is. The code he is talking about is the stored trouble code and you will need a scan tool to determine what code is it. You can visit AutoZone to have you vehicle diagnose with a scan tool and reset the codes, its free.
