SOURCE: high oil pressure in my humer h2
First thing that i would reccomend is switching to 5w30 oil since this is what GM wants you to run in your hummer. Next i assume your gauge is pegged out and doesn't fluctuate. You are going to have to take your hummer down to the local dealer and have a computer hooked up to see if the gauge is bad or the oil pressure sender is bad, more than likely the sender. thanks for using fixya !! have a nice day

for what i had experienced is to change the fuel sender unit and speedometer gauge and recalibrate the IPC to the latest calibration.

Testimonial: "Very Helpful especially when money is tight and all we ask for is a simple answer without being charged that's all ppl think about is rippin ppl off."
There is a sensor located on the oil pan. If the plug-in to this sensor comes loose it or if the sensor fails, it will send the low oil signal. You are wise to check the oil to confirm it is not low.
