Is it possible maybe the stepper motor died out?

That will pucker the old bung hole.

 

Good point John makes about the stepper motor.

 

I don't know how good this info is but could be worth a try.

When my sensor went out my oil pressure was reading 80 psi all the time.  If you have a ELM327 and the Torque app on your phone I would think you could still get a good oil pressure reading on that if it's the stepper motor.

I am by no means a wiring expert, but with the key on: wouldn't the gauge max out when you unplug the connection from the sending unit. Likewise, you should be able to use a multi-meter/probe and ground the 12v source on the harness side and the gauge should go to 0 psi. This would rule out faulty gauge/stepper motor and point the problem to a bad sending unit. Somebody else feel free to chime in.

When my sending unit went out the needle pegged. I'd bet a cluster issue.

Unplugged it and it should max out and then fall to zero. If the gauge doesnt move, its a stepper motor.
