Hello and thank you for your question,

The check engine light comes on when the computer sees a system fault and when this happens the computer will set and store a fault code. In order to know what is failing the first thing that need to be done is the system needs to be scanned and the fault code and or codes retrieved, has that been done yet?

No can I go to autozone to have it checked
Expert:  Ron replied 1 year ago.

Yes Auto Zone will do a scan for you at no charge, if you can get me the actual fault code I will advise from there.

Just checking back with you to see if you where able to get the scan done and if so what where the fault codes you retrieved. Let me know and we can work from there.
