use an ODB2 code reader, copy the error code down and clear the code. look up the error code to see just what error code your computer stored and fix the problem. or just take it nto a service dept, like a dealer or pep boys who work on cars. it shouldn't cost you much to clear the code, but if ther problem is serious, it may have to be fixed or the check engine light will just come on again after clearing the code.
