Thank you for your detailed answer. I accidently cut 2 small wires in the main wiring harness when I attemped to lift the harness over a hose connection. I repaired the cut insulation with electrical tape and carefully put the wires back into the harness. One of the wires may have shorted out since the battery was not disconnected. Now that the wires are repaired, can I delete the code or clear the code history to get rid of the "check engine light" on my instrument panel.

Thank you very much for your time and effort in assisting me with this problem.

Thank you for your analysis. While replacing the cam synchronizer, I accidently cut the insulation on 2 small wires in the main wiring harness. The battery was still connected and I am sure one of them was shorted out. I repaired the cut insulation with electrical tape and carefully laid the wires with the others in the bundle and taped the bundle.

Am I able to somehow erase the P1633 code or clear the history to get rid of the check engine light.

Thank you very much for your time in assisting me with this problem
