 Have you ruled out actual low oil pressure?  JB

Today (5 days later) I did some diagnostics by testing the light status after disconnecting the pressure sensor wire, then after grounding the pressure wire and then the temperature warning wire heading to the dash. Based on my testing everything was working as it should with the engine off. I then started the engine and the light went off as normal after it started.
