These sending units are known to fail, a replacement is about $25. I had a Bonneville that did the same thing. The only real way to test it is to remove the electronic sending unit and test it with a manual gauge. In my case I had 40 psi of oil pressure with the manual gauge but the dash would read 5-10psi.

Warning - your engine is not producing enough oil pressure and is at great risk of internal damage ($$$$$). Is the car high mileage? Is the oil level where it is supposed to be? How long since the last oil change?

Does the engine sounds like it is rattling when it runs? LIke the oil pressure is low. It might be a oil pressure sensor. If it is rattling then start with an oil change.

1995 buick lesabre limited, oil gauge issue


Could be two things, your oil pump pick tube is clog, oil pan would have to be drop to check, or your camshaft bearing worn causing low oil pressure,I would not say piston rod bearing or main bearing, cause there's no knock noise. You will have better oil pressure when cold due to oil much thicker. so I would forget about a bad oil pump.

The oil pressure in an engine will naturally drop off as the engine warms up. If the oil pressure is dropping too much it could be cause by several things. I don't know how many miles your engine has on it but the oil pump may be getting weak and may need to be replaced. Worn out cam bearings or crank bearings can also cause low oil pressure. Sounds like your engine may be ready for a rebuild

Low oil pressure after engine warms.....


A 1999 Yukon DOES NOT have a vacuum advance. It is computer controlled timing. Low oil pressure is the result of some or all of the following : worn oil pump, worn cam bearings, worn crank bearings. Oil pressure also normally drops as engine warms because the viscosity of the oil changes with temperature.
