#6 of 19 Oil light comming on
Jan 01, 2010 (4:09 pm)
I took the 2006 Jeep to my mechanic and they replaced the oil sending unit. He advised that some of the after market oil sending units will not properly function on the vehicle and will still come on peridoically. He stated that they used an oil sending unit from the dealer and the system had an error code of PO522 which was cleared. The problem has not returned. Hope this helps.

Thanks for the information. I checked with my mechanic and the unit he put on was from OEM and not from the dealer. I haven't had the time yet to get it back to him and try one from the dealer, it would be great if that solved the problem but the process of elimination gets expensive.

Right now I am dealing more or less the same problem. It began after thermostat was remove for a treatment of water mixing with oil. I found some answers that identify this kind of problem with missing thermostat. I am going to installe an original one to see if it is part of the problem. Coincidence?

Just got a 02 liberty and am having the oil light problem,, seems to be common,,replaced sensor and now comes on at 200rpm everytime. the old one had oil on it and only came on when slowing down. It has all new oil and filter and next of course will be the gauge test but we all know that will be fine. There is nothing wrong in the engine so count that out. I would like to find someone who has solved this problem,, the only one i can find in any forum is a wire short so i will tell my mech that,,,, question is ??? is there any recalls on this car as mine has very low milage and probally only used behind an rv so i am sure attention to it was at a minium. and i am hearing that there might be and of course an answer to this common problem of the oil light.
So far I have
clean ERG value or replace
oil to full
no synthetic oil
voltage on sensor / check
o2 sensor / however i am not sure what this is
pin might be in backwards
reset light sensors
th 02-03 models have sluding problems & oil pump problems
replacing computer and or parts which has not worked usually a dealer thing
blocked oil pump screen
jeep makes bad parts so use better aftermarket parts
out of all of these only fix i have seen is the wiring short so if any of you have any info please let me know so i can help my mech solve this while my warrenty is still good.

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
