2006 jeep grand cherokee oil light came on off on restart got dealer opinion of other problems. disconnected sensor and had all the same symptoms. concluded that sensor is not closing after shut off and all the rest of the on off's are to do with jeep diagnostics trying to tell me i might have a problem. oil light should come on and stay on at second key position after selftest if not change sensor beside oil filter. After hearing all this nonsense
about bad sensors I put a GM sensor in and all problems went away.

I have 02 Liberty, oil light comes on and off, replaced oil sender twice and still comes on. So I took a mirror and flash light ,place the mirror the right angle to look straight in the sender hole with the light .Guess what I found? A rubber plug floating around in there. I'm the third ower,so who knows how that got in there. Maybe it's been in there from the Jeep factory.I started the engine to see if the oil would push the plug out, won't quite come out. There's a pipe plug close to that sender hole,which is a larger hole. Going to take that pipe plug out the next time I can work on the Jeep. I know this has been the problem all along. There's been alot of blogs on this problem with the oil light coming on, Maybe there's a smart a_ _ at the Jeep factory thought this would be a funny joke . Ha Ha

My daughter had a 02 Liberty that had this same problem. Three new sensors later she still had the problem. I found out later that the OEM sensors her mechanic was putting on were defective. I have an 05 Liberty and this problem has just started with mine. I'm going to the dealer and by one from them and have my mechanic put it on. Hope I have better luck than she did, I'll let you know.
#17 of 19 Chrysler, oil and sludge
Jul 21, 2013 (10:15 am)
Having been once a Chrysler aficionado, I can look back at the history of some of the engines Chrysler has put out in the real world and tell what I have learned. My last Chrysler was a 2005 Liberty with the diesel. It died an ignominious death at 77,594 miles after the number one connecting rod failed destroying the whole thing.
But let me address some other issues here. There have been several engines put out by Chrysler than have been sludge producers including the 273, the 318, the 360, the 3.9L V-6, the 2.2 turbo from the eighties, the 2.7 L V-6, the 3.7 L V-6 to mention a few. All of these engines have internal gas and internal oil flow issues and they run quite hot inside, more so than G.M. or Ford. If you use conventional oil and change it religiously every three miles you will have an issue with sludge formation even if you drive 90% of the time on the highway. In 1993, I did my research before purchasing a Dakota pickup with the 318. After a break-in period of 3000 miles, I switched over to synthetic motor oil. In 1998 we purchased a new Chrysler Concorde with the 2.7L V-6 and kept it for fourteen years. It was treated the same way as the Dakota. The 2.7 was far worse as it use oil pressure as a means of controlling timing chain tension. Internally, the engine needed to be kept immaculate otherwise it would fail. The 3.7 has similar issues to the 2.7 and thus must be kept immaculate inside. The use of a good oil filter helps too.
I feel for those of you with these issues but unfortunately Chrysler has built a few problematic engines. If they are kept immaculate inside, then they are delightfully powerful and trouble free. If they are not well kept, you know the results based on what I have read in this blog.

Did exactly what I said I was going to do. I took the car to my mechanic and told him I wanted a factory (Jeep) oil sensor put on it. I even told him to put a Mopar oil filter on it and change the oil again. As it turned out the oil pressure sending unit was bad and leaking. I never looked under the hood and I guess it wasn't leaking badly enough for me to see any oil on the ground. Have not had any problems since.
