Default Oil pressure sensor troubleshooting
I have a 2007 Silverado classic 6.0L. The oil pressure guage is stuck at 80psi. Trying to determine if its the sensor or the wiring. does anyone know how to test this?

THANKS IN ADVANCE FOR THE HELP

Default More info
I took the connector off the sensor and the guage is at zero. Does this mean the wiring is not grounded? There is resistance to ground on all three wires.

Welcome to the forum. The BLK wire should have continuity to ground. Either the PCM is not supplying a good ground on that wire or the wire has a broken/corroded section.
