Question about 2001 Oldsmobile Aurora
Low oil pressure light goes on and off until the car reaches full operating temperature. The car runs fine. I checked the oil level and it's full. Do you know what causes this?
The oil pressure sending unit has gone bad. I sending unit is just above the oil filter and you can get to it from the top. When you face the Engine look down towards the oil filter, the oil pressure sending unit is just above that and it looks like a cylinder with two wires coming from it. If you don't see it, it's right between the exhaust manifold and oil filter.
If you go to Auto Zone or Parts Source, they'll have the oil pressure sending unit and the step by step instructions, When installing the new sensor. Do not use teflon tape or any sealant, the sensor is tapered and need's the good ground from the engine to give you right readings.
Good luck and hope this helps.
