Best Answer

The Check Engine light is on because the ECU has detected a problem with the emissions system. The ECU needs to be scanned with a scan tool to help diagnose the problem which can be a multitude of things from a loose gas cap to a failing sensor or worse. Seek out a trusted professional or Honda dealer for repair.
