I'm guessing you mean the check engine light. This will come on after a certain mileage to indicate there is some scheduled maintanence due. It may also come on if there is a problem somewhere. Attach an OBDII reader to the diagnostic port on the car and then look up the code at a obdII code site ( Google search) to see what the problem is. Many auto parts will read your code at no charge in the hopes that they can sell you a part. Get the code and go home to look it up.
