How to reset service engine light on 2001 cavalier???
HelloCustomer if the check engine light is on then it means that the vehicle has detected a problem. You can have the computer scanned for codes for free at most autoparts stores. Come back here and I can let you know what is going on. While you are at the parts store you can also use the cimputer scanner to turn the light off to see if it comes back on.
