oil pressure stuck at 80 pounds in my 06 Tahoe 5.3L
The light should extinguish itself after inflating the offending tire to the correct pressure. If it does not, you probably have a bad tire pressure sensor.
The oil pressure gauge will fluctuate on a Chevy Tahoe when the vehicle is idling and when the vehicle is driven at highway speed. Idle is usually 30 psi oil pressure or slightly more. At highway speed, the oil pressure should be between 60 psi and 80 psi.
The oil pressure switch on a 1997 Chevy Tahoe is located on the back of the engine. It is in the center-rear part of the engine.
On a 98 Chevy Tahoe, the transmission fluid pressure switch is located on the valve body. It is found to the right of the engine.

One of the causes for low oil pressure in a Chevy Tahoe could be a clogged or dirty oil filter. Changing the filter may get rid of the problem.
