1999 buick ultra 129 psi oil pressure?

[460Stanger]

Does anyone know if 129 psi means anything other than a broken (or disconnected) oil pressure sensor?
Car runs great, oil pressure has always been ~60 psi
Check gauges light comes on so I look at the digital oil pressure and it's locked on 129 psi -

I'm not sure where the oil pressure sensor is? I drove through some deep snow that was up to the oil pan a day or so before the warning . . . could that have caused it?

Thanks gents,

The sensor is located at the right hand rear corner of the engine, below the power steering pump.

sensor/wiring problem, your oil pressure is fine.

Thank you, nice to get a little reassurance before I start poking around. There's alot of good minds on this site, and I thank you for sharing.

Ive seen the relief valve stick from being worn and cause super high pressure.
usually that will blow the filter apart.

pretty wicked when that happens

best to check the pressure with a manual gauge to be sure.
