You can test your 1997 Oldsmobile 2.4 liter engine oil pressure sending unit with a diagnostic tester. The diagnostic tester is the most reliable way to make sure your sending unit is working properly.
The oil sending unit on the 1994 Oldsmobile Cutlass Supreme is located on the top of the engine compartment. It is directly above the oil filter.
back of engine, passenger side, above oil filtre.
The oil pressure sending unit is located up on the head near the pulley for the power steering pump. It is on the back side of the head. I had to replace mine. It is an easy job.
Check the oil sending unit first, if this turns out not to be the problem then you might have a bad oil pump. If this is the case you should invest in a repair manual for vehicles that carry your make and model and year of car I bought mine for about 20.00$. good luck.
Just to the drivers side of the engine next to the distributor.
Which engine is in this car?
On the 3.4, directly above and to the right of the starter.
Plug has 3 wires.
AnswerThe oil light comes on when you have low oil pressure or low level. First check your oil. If there are no unusual noises coming from the engine, perhaps the sending unit itself may shorted to ground. Also the pressure relief valve from the oil pump may need adjustment. (That is nothing but a bolt and a spring.)
Remove oil sending unit and replace with a mechanical gauge to check actual engine oil pressure
