    I just encountered the same problem this morning. I will be looking into it. I have 164,000 miles. I will probably be hooking up a mechanical oil gauge if I can find the oil sensor. The crank and cam bearings may have excessive clearance causing the same low oil pressure problem.

    I get the low oil light, but only at hot idle in the morning when idle drops below 600-700 rpm. 131,000 miles on the clock. I sure hope its not the oil pump. Let me know what you find out about the mechanical oil pressure gauge (ie where you hooked up, cold idle pressure, hot idle, etc.)

    Thanks.

    I have the same problem. I found the sending unit, it is above the filter. With the filter off I can reach the unit but can not see it to find out how the clip works. Any ideas? I can not pull the connector off.

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.

It could be a worn out oil pump or more serious engine problem. With 189K miles, there is a good possibility that a major overhaul may be necessary. Is this economical to do or do you opt for a replacement engine? Have a mechanic check out the oil pump first.

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.

2004 jeep liberty. oil light come on some times. today on tomorrow off sort of thing. checked oil and full. 2000km from last oil change. what are other reasons for oil light to come on?


other reasons:

perhaps it has too much oil in it? is it right on the fullmark, or above?

solution - drain some out by carefully undoing the sump bolt and holding it so only a dribble comes out, its usually one litre between E and F on your dipstick.

check your motor belts(fan, alternator, aircon) have any fallen off or are loose, some cars have vacuum pumps powered by the belts that maintain oil compression in the engine.

poor compression in your cylinders perhaps, symptoms of a worn motor
get a engine compression test done.

your oil pump may be getting wornout, this is a pump within the engine that pumps the oil from the bottom back upto the top so your motor is properly lubricated, no real way of testing this, try replacing this as a last resort, its usually cheaper to put a 2nd hand replacement motor in.

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.

Squeels at start for first two seconds


The squeeling could be from a worn belt or if oil drips on belt overnight. Replace the belt first to see if that fixes it.Good luck.

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.
