Why is the oil pressure on my Chevy Tahoe too high?

The oil gauges on the GMT800 platforms are known to go bad (mainly the sensor), thus causing them to be pegged past 80 PSI. Too high of oil pressure is bad as seals will be blown. Your best bet it check the oil pressure sensor and see if it needs to be replaced. There could be a loose wire somewhere also since you did say you had some work done.

Is the oil in my Chevy Tahoe leaking?

I finally seem to not be leaking any fluids. After the first fix, the brand new oil filter gasket blew, and we went through 10 quarts of oil in a weekend just keeping it running until we could it to the shop on Monday. Anyway…I got totally side-tracked by being all annoyed about this again…

Why is my oil Gage stuck at 80 psi?

Once I turn my truck on my oil gage automatically shoots straight up to 80 psi. If I turn turn the key forward without starting the vehicle it stays at 0 but once the truck is on it goes straight up to 80 and doesn’t move while driving. My car has 140000 miles.

Is it normal for the oil gauge to read 0?

When the engine not running it is normal for it to read 0 since the oil pressure is created by the engine running. To have this corrected, I would recommend having a certified professional from YourMechanic diagnose the odd oil gauge behavior and assist with repair.

How can I tell if my oil pressure sensor is failing?

This is a common sign of a failing oil pressure sensor. This is a small unit in the engine block that reads oil pressure inside the motor and relays this information to the vehicle’s computer as well as the oil pressure gauge.

Where is the oil pressure sensor on a Silverado?

It is on the top of the block on the driver side behind the intake manifold and has a wire connector plugged in to the top of it. It is more likely the sender and not a stepper motor, especially if all the other steppers are working correctly. Plus, it is much easier to change the sensor than a stepper motor. Went and bought a sending unit.

What’s the oil pressure on a GMC Truck?

When I got it pulled over and stopped, the gauge was just staying maxed no matter the speed. Once it was stopped I let it sit and put the key into accessory after a while and noticed the gauge went from 0 (when it was turned off) to 80 before the engine was even running – just in accessory. Now, how in the hell could that be?
