OIL PRESSURE GUAGE HIGH

1994 Ford Explorer • 16,000 miles

My oil pressure gauge goes all the way up past normaln well the service light goes on is it the vaccum valve that is giving to much air pressure and it seems like it might turn off so what can I check or do to fix the oil pressure or can it be a oilpressure sensor

To test the lubrication system a good technician will test for engine oil pressure (with a pressure gauge) and if oil pressure is good then the only other issues are electrical. The engine oil pressure sensor, wiring from sensor to instrument cluster or the instrument cluster itself. Some rare occasions engine oil sludge has plugged or restricted the hole opening to the engine oil pressure sensor causing a false oil pressure reading. So you may what to look at the engine oil pressure sensor first for a high pressure reading. Engine oil pressure should increase when accelerating and drop back down to normal at idle.
Do you have the correct engine oil in the engine and do you change the oil and filter regularly?
Engine sludge can cause high oil pressure by restricting oil flow through engine.

I'm not sure what vacuum valve you mentioned in relation to engine oil pressure.
Let me know if this answers your question or if you have any more questions.
Talk to you soon, TY
