    It registers as high as possible. If I rev the rpms up it goes to zero. When I off it goes back up.

The switch is on the back of the block towards the firewall. Did the gage quit or? Hope this helps. Thanks;

    I would change out the sender. If you have no knocking, then you have oil pressure. Do not put tape on the threads of the sender as this will not allow it to function.

    Thanks for the rating.

If my 2004 chevy silverado oil pressure gage stays at 80 psi could this hurt the engine

I would want to know what the actual oil pressure is. The sending unit or the gauge on the dash could have failed.
There is a pressure relief valve to prevent oil pressure from going too high, but staying at 80psi would not be good for a long time.

I have a 2007 chevrolet avalanche LT and everytime im driving it after a couple kms it will say low oil pressure turn off engine????

Hello: What weight oil is in the engine? How many miles since last oil change? How many miles on truck? The first thing you could do is replace the oil pressure sensor. You will have to remove the intake manifold to gain access to the oil pressure sensor. If the engine is not knocking or there isn't any valve train noise then it could be the oil pressure sensor when this message is displayed.

2003 Chevrolet Avalanche, 5.3L 4WD. Oil Pressure pegs out at 0 when cold. Was told to replace the oil pressure sensor, but no one knows where it is......... Help? Please?? LOL

Oil pressure sending unit is located behind the intake, reach your hand behind the intake a little to the drivers side and you should feel the sensor

My oil pressure gauge is bouncing all around on my 2003 Chevy Avalanche. It bounces from the low end to the high end and everywhere in between. Any idea what might be causing this?

Sounds like the oil pressure sensor. Thatt is the easiest thing to change. If not its the gauge. Put voltage to the wires from the switch and see if the gauge stops jumping and stays pegged, if it does its the switch Good luck

The Oil Gauge of my 2004 Avalanche drops to cero while driving, it doesn't stop the engine or any other system, no noise, no nothing, it just (the messurement) goes crazy until droping to cero. When I stop...

If the tech used a oil pressure gauge on your engine to see if the pressure was good he should of checked the oil pressure switch next. If that proved to be good the gage in the dash is bad. How hard is that to do at any dealership that sells these vehicles. They are require to have all the equipment to service these vehicles to stay in business coordinated by the francised rules. Call the corporate office and file a complaint towards that dealer and demand a refund
