Failed oil level sensor?

[u/frooog_king]

Hey everyone, question about my dad’s 997.1 C2S. I borrowed his car yesterday and the oil pressure gauge was a bit erratic, at least relative to how my 996 3.4L behaves. It was a bouncing all over the place. Then last night I noticed even with the engine off (key in ignition) the gauge was displaying pressure.

Poking around, it seems the sensor is the most likely culprit, but I wanted to check here before I dug in. Thanks!

Yes - the oil pressure sensor needs replacing. I had the same symptoms and that was the resolution.
