You need to reset the light with a scan tool, the same one you used to read the code in the first place.

You need to have a code reader/scan tool hooked up to retrieve the code/s that triggered the engine light. You can have this done at most auto parts stores for free. Try Auto zone, Checkers, Napa, or Murray's. The engine light will eventually go out if the computer does not receive any codes after many cycles turning the ignition on and off. It will not go out if there are codes still present. After you've retrieve the code/s bring them back here and we will have a better understanding of what caused them.
