Check engine light comes on when the computer detects a problem with the emmissions system. A code will be stored in the computer's memory, pointing to the fault. This could be nothing more than a loose gas cap. It can also mean a more serious problem. Have the computer scanned for trouble codes.
Check your gas cap.....My check Engine light always comes on if it is loose or not on at all.
