Oil Pressure Gauge	Sign In

My girlfriend's 2002 Pontiac Bonnevilles oil pressure gauge is stuck. It always reads like there is a high pressure problem. Would this be caused by the sensor/sending unit and if so where is it located and is it hard to change?

Sending units are usually near oil filter but if gauge is stuck that won't fix it. Unplug it and see if the gauge reacts, T

Re: Oil Pressure Gauge	Sign In

My girlfriend informed me that the gauge does go to zero when the key is off. Do you think I still need to unplug the sensor?

Guess here: Try a new sender. A thin wrench open end should get it out -- check for leaks with new one if you try that.

In general engines are regulated by a spring that doesn't allow real overpressure of oil and will bypass oil filter and get oil to the most important bearings in engine first.

Never saw one fail to too much pressure?? Oil pressure can be checked by a gauge put in where the sender goes.

All problems in my career where low oil pressure usually caused by a worn engine or once a bad oil pump.

I would check this out as too much pressure about surely would cause problems, T
