1. Check your oil level. If oil level is not ok, correct oil level and find out why oil level was low and correct the problem. (Leaks, bad PCV, Burning oil due to severe engine wear, nobody has bothered to check it for the last 3000 miles, WAY overdue for an oil change, etc.) If oil level is ok, proceed to next step.
2. Remove the oil pressure sensor and install a manual oil pressure gauge. Run engine to verify low oil pressure. If gauge shows that the oil pressure is low, overhaul or replace engine. If oil pressure is ok, replace oil pressure sending unit and retest.
Your oil sending unit is located somewhre on the engine. It will be round and about 1 to 1.5 inch across. It will have a wire attached to the top of it. I dont know the specific location on your particular car.
What does it do? It is a diaphram operated device that sends a signal to your oil gage or warning light. The engine side is exposed to oil pressure in the engine. The oil presses against the diaphram. The diaphram is attached to a variable resistor device that operates the gage. Low pressure on the diaphram -= low signal to the gage; Hight pressure on the diaphram = high signal to the gage.
OIL PRESSURE SWITCH-I'm not sure if this is the gauge sender, though.
1995 Jeep Grand Cherokee 4WD 4.0L MFI 6cyl
The Oil Pressure Switch is located:
Under hood, passenger side, lower engine area, above oil pan, mounted in engine block.
Did you check the oil? If it is full, there is something wrong with the sending unit. The oil light is not for oil level but for pressure, it will still read 60 lbs pressure with 1 qt of oil in there. So, if everything checks out, you will need to replace the sending unit, usually found near the filter, sometimes on the pump itself or on the side of the engine, down low, looks like a temp plug with a wire stuck to it. Hope this helps.
The oil sending unit has gone bad and needs to be replaced. The sensor is under the exhaust manifold and above the oil filter on the V6. Replace the oil pressure sending unit, once they fail they may start to leak oil soon. Good luck and keep me posted.
the oil sending unit is located on the front of the engine(this is facing the passenger side fender.) to access it take the front tire off on passenger side you will see the oil filter and a sending unit right behind and above it it will have a green colored plug. please rate this. thanks
