Asked by Nebraska1963 Jan 26, 2017 at 11:05 PM about the 2006 GMC Sierra 1500 SLE1 Extended Cab 6.5 ft. 4WD

Question type: Maintenance & Repair

I have a 2006 GMC Sierra 1500 pickup. My oil pressure gauge is as high as it
goes (80) but when I take off from a stop it drops down momentarily and then
jumps right back up to high (80). Any ideas as to what my be wrong?

Sounds like a faulty oil pressure sender, and while your right there make sure the little screen is nice and clean that sits just below the sender assembly inside the tube.
