Hello,

The check engine light comes on when the vehicle's on-board diagnostics detect faults within the engine management system. It could be any number of sensors or parts. It can also be due to an emission issue.

What you need to do is to have the vehicle scanned and retrieve the code(s). This can help you determine what the issue might be.

Please let me know what you find or if you have any questions.

Thank you.
