Hello and welcome to JustAnswer! I apologize for the extended wait time you experienced, I've only just come online now and would like to assist you with your question.

There are dozens of possible causes for the engine light coming on. The light comes on when the engine controller sees a failure in a monitored component and sets a fault code. The issue could be many things including ignition system issues, fuel injectors, wiring, any sensor, a transmission related issue, catalytic converter efficiency, an evaporative emissions system failure or leak including a loose or bad fuel cap; literally a failure in any powertrain component can cause the light to come on.

The first step in diagnosing the problem will be to use a scan tool or code reader to see what fault codes are setting and then testing can be done from there based on the findings.

My goal is to give you the best experience possible! I hope I have earned a 5 star rating! Please remember to rate my service by selecting the 5 stars at the top of the screen before you leave today. If you need more assistance, please use the reply box and let me know.
