Low oil pressure or a faulty sensor. First thing to do is to replace the oil filter with an AC/Delco filter. This is an excellent filter designed for your Cadillac. If that does not solve the problem, replace the oil pressure sending unit. If that does not do it, then an oil pressure test is in order, to determine if the oil pump is faulty. try a heavier grade of oil it worked for me
The pressure is lower as the engine is at slower rpms. The oil filter could be clogged or the oil pump might be going bad.
Stop running this engine until you find out why the oil pressure warning light is on. You have low oil pressure. This can be caused by low oil level, defective oil pump, defective oil pressure sending unit, incorrect oil filter. First thing before proceeding is to Change your oil and install a new oil filter, I recommend Purolator.
The oil pressure switch is located on the oil filter adapter. Find the oil filter and you should see the oil pressure switch.
It is normal for the pressure to drop. It depends what you mean by "very low". Check the oil level and the condition of the oil and filter. The oil and filter may need changing.
Low oil pressure or defective oil pressure sending unit. Can be low if oil or the oil pump is failing. Check the oil and if it is full replace the oil pressure sending unit. If this does not solve the problem, change the oil and replace the filter with a quality filter, such as Purolator. Make sure you are using the correct weight oil and the correct size filter. If the problem persists, then seek professional help and stop driving this car until you do.
The 1995 Nissan Pathfinder oil pressure sensor can be found next to the oil filter. The oil pressure sensor measures the oil pressure in the engine.
Low oil pressure = Oil pressure has dropped, STOP Check engine = Problem with the emission's system. Temperture = Engine overheating, STOP Maintence required = Some sort of maintence is due, normally Oil/Filter change.
I would say you have low oil pressure. Change the oil and filter. Use 5w20 oil or 5w30 whichever your owner's manual lists, and install a quality filter such as Motorcraft, Purolator, or Wix. Do not use any other weight oil. If the oil pressure is still low stop driving the vehicle and seek professional help.
Incorrect filter, defective filter, weak oil pump, clogged oil pump strainer, clogged oil galleys, worn engine bearings, defective oil pressure gage, or defective oil pressure sending unit.
oil pressure relief valve is usually located in the oil filter housing as a failsafe for if the oil filter blocks up.
