No shouldn't I garentee the problem is with the oil presure switch. if it is a 4 liter it is located on the passenger side on the block with a green connector on it. If it is a 4.7 it is located on top of the oil filter. The switches are very cheep about 10 bucks I would replace it if the vehicle has high mileage.

I have a 2002 jeep Cherokee oil gauge show max out when i start the Eng


When oil is cold, pressure will read high, but as it warms up pressure indicator should drop to normal. Are you using the correct weight oil for your weather conditions? Running straight 30 weight, or say 20w50 could cause this issue.

I just bought a '02 Jeep Grand Cherokee and the oil press. indicator is always on H. I heard the engine during idle making a "clancking" sound which i heard before in cars with the wrong oil type...


I would recommend changing the oil and filter, using the correct oil. It's possible the wrong oil could cause the noise. Wait and see if the oil change has any effect on the oil pressure reading. If it doesn't, change the oil pressure switch or sending unit.

My oil pressure gauge is reading high, if the car is turned on and parked, or when ever I stop, the car is giving gas as if i was stepping on the gas pedal.


have oil pressure checked to see oil pump is faulty.make sure your oil is the right viscosity if too thick that will cause high pressure.if all is good.your pressure gauge is faulty.

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

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.

Engine light on/Oil Gauge on stays on high


Any waranties left? Is oil full? Any noises from engine? Did you put a mechanical gauge on it and check "real" oil pressure? (I would not drive it 'till I was sure about actual oil pressure!!)

2002 Jeep Grand Cherokee 4.0L Oil gauge reading very high


If the weather in your area is colder than normal, your startup oil pressure will reflect this, essentially because it is much thicker when very cold. This high reading should drop to "normal" once it reaches operating temperature. This condition can also be caused by a sticking pressure relief in the oil pump, usually caused by sludge inside the engine. If you regularly maintain your vehicle and use good quality oil, this should not happen. The oil pressure sending unit is also suspect, but in your case, I would not put it at the front of the list. If oil is close to "change time" consider using a good synthetic oil (synthetics flow better at extreme temps) or using a 5W anything oil during winter months. (see manufacturers specs)

Might be that the oil pressure switch is going out. Unless this has been happening for a while now.
