Default Oil Pressure

Driving down the road and looked down at the water temp gauge and noticed the oil pressure gauge is Maxed out !! I immediately slowed down and went to the DIC to double check the pressure. It was telling me 130psi !!! I've spun bearings in previous vehicles and it makes a hellava lot of noise and the engine normally seizes. I'm out in the middle of the desert 40 miles to the closest town, so I continued to drive it.
Does anyone have any ideas ? Sender failure ? Shorted wire to sender ? Surely, if the oil pressure was that high, the filter would have hand grenatted.

Most likely your oil pressure sending unit crapped out. Pegs at 80 psi on the dash gauge when that happens.

Yes, its your oil pressure sensor at the back of the block under the cowel. Happens to everyone at some time or other. Anyone who has a car where it has never been changed, should save yourself a headache and do it ahead of time. Cheap and easy to do.

Super common failure. Sometimes people will relocate the sender so you don't need to pull the intake when (not if) it fails again.

Don't bother shopping around for one, either. They are all garbage. Brass housing, aluminum housing, AC delco or Driveworks... all crap.

Get the lifetime warranty one from the parts store so you don't have to pay for it again.
