Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.The check engine light come on when the computer sees a system fault and when this happens the computer will set and store a fault code and or codes. In order to determine what is failing you are going to need to start first with having the computer system scanned and the fault code and or codes retrieved. If you can get this done and post back with the results I will see if I can help you with this.
