I have a 2005 Chevy Silverado with 5.3 . The oil pressure gauge a few weeks ago reads 80psi instead of the 40. Now if you put a load on the engine it shoots to 0. Let off gas it goes back
If the gauge is correct your truck wont last long, sounds like a blockage in the oil passages. But more than likely the oil sending unit or gauge has failed. Make sure you have proper oil level
Hello, this problem is due to a failing stepper motor. The stepper motor is the motor behind the gauge that controls the movement of the needle. When a stepper motor begins to go out it will cause the gauge needle to stick, skip around, stay at zero or max out on the gauge. The only way to fix the problem is to replace the stepper motor with a new one. While replacing one motor it is best to go ahead and replace them all as the others will go out in time as well. Your cluster will have one motor for each gauge. Search Google for DrSpeedometer for more information and to find out how to get your cluster fixed.
