Our '04 Liberty has been doing this for a while, but it's sporadic. Sometimes you start when cold and the light comes on, so I wait for a sec or two for pressure to come up and then I have to shut off the engine and start it again to get the light to shut off. I don't know if it is the sending unit or the pump is not building pressure quick enough. Another thing it could be (hope not) is the engine bearings are worn but I'd have to run a pressure test to find out. Sometimes I can hear the tappets clicking when I start it so who knows.

I was one of the first ones to post this problem hoping to get some answers from others with the same problem and I did. After dealing with my mechanic for months I decided to take it to the dealer. I knew this would be a nightmare but I did it anyway. After about 30 minutes the guy comes back to me and tells me the engine is sludged-up and it will cost quite a bit of money to repair it. I bought it new in 2002 and changed the oil faithfully every 3,000 miles, give me a break. I didn't even bother to ask him how he knew that without taking anything apart. I hate it when somebody pours something down your back and tells you it's raining. Well bottom line is it's someone else's problem now.

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
