Question about 2002 Jeep Liberty

Oil pressure light comes on after driving on highway for 10 miles

I have a 2002 Jeep Liberty (91,000) and my check oil light started coming on last week. I drove on the highway to work (10 miles) and the oil light came on when I stopped to turn onto another road. It went off and I drove about a mile to work. The light came on again. I went to a shop by my work and they couldn't look at it until the next day. I drove home. When I got at the 10 mile mark the light came on again. I drove about a mile to a shop by my house. The light came on again.
I had had the oil changed the week before and they suggested checking to see if the oil resend unit had been jarred. I went a couple of blocks to the place and they checked the oil, the oil filter and the unit and said it was fine. I drove the next several days, just staying in the neighborhood, and the light never came on. I went to work this morning and at the exact same intersection the oil light came on again.
Any thoughts why driving 10 miles at 65 - 70 causing the light to come on, but driving 10 miles at low speeds doesn't cause the light to come on?

    I drive a 2002 Jeep Liberty Sport. I had an oil change a month ago . .all fine. A month later my oil light came on so I checked my levels since I thought there might be a slow leak. A little low but otherwise ok. I put a quart of oil in to bring it to safe level and light kept coming on (at least 3 times in 5 miles) I took it to a mechanic who ran a diagnostic and ended up replacing a oil gauge. He recommended I see an engine specialist because the oil light was still going on speratically at high rpms. The next day I started my drive to work and my oil light went on every 45 seconds regardless of speed. I unfortunately couldn't park the car for 5 miles and the engine didn't seize, but right before I made it to my destination every light on my dash lit up including the seatbelt light. Now I am concerned that I have an electrical problem and an engine problem . . .help.

    I also have a 2002 Jeep Liberty, with approx. 96,000. After driving on the highway, when I came to a stop and/or the RPM's dropped below 1000, the oil light would come on. Like everyone else, I have recently had an oil change and checked the oil gauge, which is in good range. Any ideas?

Sounds like your sending unit sensor - if it was your pump going out, your engine would be history by now. Rule of thumb, if your oil check light ever comes on, it's usually too late to remedy the problem. You have a major issue, but since you've obviousely drove it quite a bit since then and it still hasn't seized up, I'm guessing you're ok...for now. Since you took it to a shop and they said you're ok, I'm assuming they checked your level and visually checked for leaks and found nothing. Either, you've got somethijng partially blocking your pick-up tube for the pump which is in your oil pan, or a electrical issue with the sensor. I would start by having someone check the sensor out and go from there...good luck.

Oil light came on when the weather turned cold. Garage put in new light sensor. New oil. Oil cleaner. still comes on when it is cold out. goes off when engine has heated up (around 20 miles)


you need that checked out asap. you cant drive with the oil light on for 20 feet. 20 miles? if it really doesn't have oil pressure for 20 miles, your engine is toasted. have the oil pressure verified with a mechanical gauge, if you are lucky, its only an electrical problem.

Just bought our 2002 Jeep Liberty. The oil pressure light came on shortly after we bought it. Took the Liberty in for an oil change right away- pressure is fine, no leaks. The light is still coming on and...


How do you know the pressure is fine? What is the pressure? Either the engine is bad, or the oil pressure sender is lying, you need to know ASAP.

Does it come on when its at a low idle? If so its probably the oil pump that is on the way out or the main bearings. It could be as easy as as wiring that is going to ground from the sensor.

Oil pressure light keeps coming on when car is at stop , or just when engine is running , but when you start moving light will come off


Am currently having the same problem. Waiting on dealership to let me know if it is the sending unit or oil pump. I am being told to not drive the car far distances or let it sit to idle for a long period of time.

I've never seen an oil pressure sensor that costs $750...Likely something else was done to justify that cost. If the light has not come on since the repair, I'd assume that problem has been corrected. If not, have the thing checked out again. If they charged you to repair it, then it should be fixed or, it's their problem!!! You should not be afraid to drive your vehicle. It's a machine, therefore it can and will break sometimes as do all cars. But being afraid to use it is not a solution.

Yes you have to check your pressure with a mechanical gauge first. If the pressure reading is good replace the oil pressure sending unit. They are known to go bad, and oil pumps going bad is rare.

2002 Jeep Liberty oil pressure light comes on in cold


Chrysler mounted the oil sensing unit on these motors directly above the oil filter. It is very easy to accidently hook the sensing unit with the oil filter wrench and crack or break it. For anyone whose oil light problem developed right after an oil change, this may be the problem. To change the unit, pry up the plastic retaining clip with a screw driver and unplug the wire harness. If the plastic part of the sensor is broken, (or if you break it to facilitate easy removal), you can remove the sensor with a 27mm socket. Once you have removed it, use a piece of CLEAN pipe cleaner to insure the hole isn't plugged with sludge which could also cause the oil light to come on. Screw in the new unit finger tight, then snug up with a WRENCH. You cannot use the socket to tighten it as it would damage the plastic part of the new sensor. Plug the wire harness back on, then start the engine to make sure it doesn't leak oil around the new unit.
