Ok had the known codes pop up a couple weeks after an oil change. Unaware of the oil used and it had an STP filter. So I changed the oil put in Mobile 1 synthetic and the update UPF48R delve filter. Fired it up. Still no pressure on the gauge and still p0523 code. Replaced the sensor. Lasted for 2 days. (DORMAN sensor) then it happened again. Decided to drop the pan and replace the O-ring. Fired up the Yukon and still had the P0523. Soooooo went and bought yet another sensor. This time a carquest premium. Cleared codes and pressure started reading. Right up to 40 bars at idle. The screen has been removed under the sensor. A GM tech told me they never replace them. My question code the o-ring failure damage the sensor? I’m at a loss and about to burn it down.
Oil pan was clean. No sludge. For 135k she was real clean inside it.
