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 comes on when the computer sees a system fault and when this happens the system will set an store a fault code and or codes. In order to know what is failing you are going to need to scan the system and retrieve the fault code and or codes that should be setting. If you can get this done and post back with them I will see if I can help you determine what is causing this issue.
