Default Oil pressure gauge reading sky high

My oil pressure indicator, both digital and mechanical, is reading 130 psi. Is that the sending unit? The car runs fine, no noise or anything. Anyone have any ideas? By the way, it's a 99 corvette.

See my sending unit just did the complete other way. I replaced my sending unit and it works fine now... Mine is a 99

If you have a mechanical gauge hooked up that reads the same, probably not the sending unit. Did you just do an oil change? Did you use 80W90?

I'm sure he's talking about the gauge on the dash and the electronic one desplayed in the DIC (Driver Information Center) when you select it.

I told him that it is probibly his oil sending unit as well. But what can I say, he is a vette owner, and he doesn't listen to well... lol

Be sure to relocate it since you are in there. These little guys are notorious for being D.O.A.

I 2nd that motion.

If it's a SINGLE wire op sensor, then all you have to do is ground it with the key on, if the gauge reads 0 with it grounded, then bad sending unit.

If it's got more than one wire DO NOT GROUND ANY WIRES WITHOUT LOOKING AT A SCHEMATIC FIRST!

just as a follow up fellas.

We replaced the O.P. Sender unit and that fixed his problem.

I was pretty sure it was the sensor, but i told him i would check into it for him.
