Try unhooking the positive battery cable for about 3 to 5 minutes. This will clear all active codes. Hook the cable back up and run the car around, see if your light comes back on. If it does, then you need it scanned again for another problem, or a problem in that same circuit(bad plug in connector, or maybe a broken wire. Good luck on your repair.

Disconnect the positive battery cable for 3 to 5 minutes to clear stored codes, reconnect it, and drive the vehicle. If the check engine light returns, scan again for another fault or a problem in the same circuit, such as a bad connector or broken wire.
