These are my ONLY opinions and only suggestions: Low or too high Engine Oil level. Contaminated Engine Oil. Low Engine Oil Viscosity. Wrong Engine Oil Grade. Malfunctioning Engine Oil Pressure Sender unit. or just a Faulty Engine Oil Pressure Gauge. thanks
Check the oil level on the dipstick to verify the oil is full. If it is, the sending unit for the gauge is most likely bad. To confirm this, turn the ignition on but don't start the engine. The red oil pressure light should be on (looks like a little red oil can). If the light is working but the gauge isn't, replace the sending unit for the gauge. Hope that helps! Jim
Oil pressure sensor I have a 2002 GMC Sierra with a 5.3L l that I had to change it on and I also have a 2012 GMC Yukon Denali with a 6.2L and the same thing happened but the 6.2L is very hard to get to at the back of the motor and the 5.3L is fairly simple.
