2001 Jeep Cherokee Sport Oil pressure and temp gauges

Ever since I got my 2001 Jeep Cherokee Sport, the oil pressure gauge and the coolant temp gauge have not worked; Both gauges move to almost the same position when the ignition is on or the car is running (they read just under the half way mark on both gauges, and they do not move otherwise. I have replaced the temperature sensor, and the oil sending unit, without any success. Any ideas?

Did you check the fuses and/or relays to make sure they are ok?

    Yeah, all the fuses are good, and the relays are all new.

SOURCE: 2002 Jeep Grand Cherokee 4.0L oil pressure gauge reading too high

if the gauge starts a 0 - goes to 1/2 , than full - sounds like gauge is OK - seems to me like the sending unit is bad - you could try removing the sender and trying to clean out the port with "brake clean", letting it dry than re-installing it. the pressure switch is still the least expensive place to start

I have a Grand Cherokee 2001 4.0 6cyl. Thermostat replaced, oil sending switch replaced but still losing coolant fluid. About from full to indicator light in six weeks. My oil pressure gauge went to...


hate to say it, but sounds like a blown gasket or cracked head - the mere indication of the white mily substance.
If you haven't done so, it is time to do a compression test.
Alternatively have you checked your oil pump itself?
Best regards

The oil pressure guage on my 2000 Jeep Grand Cherokee is registering 0. My oil was just changed and I don't see any indication of oil leaking anywhere. Could it be the sensor?


First off I wouldnt drive your car until you make sure that you have indeed oil pressure and that the gauge is a false reading, driving your car if in fact it has no oil pressure will severly damage your engine, but firstly i would check the oil pressure switch its located on the passenger side of the engine right back from the oil filter make sure the connector is clean and free from oil and corrosion if the connector appears to be in good shape take a paper clip and insert it between the 2 terminals inside the connector your oil pressure gauge should peak at 80 PSI that tells you that your gauge and all related wiring are good and in working condition, secondly remove the oil pressure switch and hook an manual oil pressure gauge up to you engine and start the engine the guage should have a oil pressure reading anywhere from 30 PSI to 55PSI depending on engine temperature if theres oil pressure on your manual gauge replace the oil pressure switch with a new unit, if you still have 0 PSI on your gauge then stop your engine immediatly and start looking at your oil pump and lubricating system for a problem.

1995 jeep cherokee sport 4.0L. Oil gauge keeps sending false message ie. jumps from almost center past the highest point on the gauge. How do I fix this problem? where is the gauge sender located?


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.

1999 Jeep Cherokee Sport 4.0L engine. Oil


I'm assuming the engine is still running and no engine noise has occured due to loss of oil pressure, and it is just the gauge that is not reading? If so, the oil pressure switch that is located on the camshaft sensor, could have a bad connection or the oil sensor will need to be replaced. The oil sensor is located on the left side of the engine and is mounting horizontally on the camshaft sensor housing.

2001 jeep cherokee compression guage at 80


generally it turns outto be one of three things 1. bad sending unit (switch) 2. stuck pressure relief valve in pump (not often) 3. bad gauge head (less than not often)(rare). You can attach a mechanical gauge to the engine and read actual oil pressure (attaches right where sender screws in). That will tell you if the problem is inside the engine or in the gauge system. If it turns out to be inside the engine you can add Marvel oil...many times the problem will clear up in a few days.
Be aware though that very high pressures can cause the oil filter to split or the seal to leak.Most quality filters are tested to about 100psi.(no idea about cheap ones if the test them at all)

Oil gauge won't stay up


It sounds like most likely its your Oil pump, if you have no pressure at stop and when you hit gas it sets the C/E light off, Guages in dash wont set off Check Engine Light. Replace Oil Pump.

Oil Pressure Always Runs High - 2002 Grand Jeep Cherokee


If your oil pressure is running in the red this would indicate too much oil in the system. You should have your oil changed and refilled soon or you run the risk of burning out the oil pump. At idle your pressure should be just over a quarter of what your gauge has. At highway speed it should not exceed 3/4 of the gauge unless your going in excess of 100 MPH. Change the oil and filter and your vehicle should be fine.
