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.

I have a 2004 jeep liberty, when the vehicle is at a stand still the oil light comes on, as I start to drive and continue to drive the light goes out. Comes on again at times when standing still,...


1st thing to try is to replace the oil sinding unit, if the problem percets then have someone install a manuel oil pressuer gauge to check the oil pressuer at hot idle if oil pressuer is less then 10 psi at hot idle then replace the oil pump.

Oil light came on after oil change and new filter. garage said I should change the oil and another new filter. No good results. Oil light is still on, what now. Jeep liberty 2005


do not start vehicle ,drop the sump and clean it out with caustic ,also the oil pump pick up pipe ,then put the oil back in and start ,if ok then put half a litre of diesel into the oil and 3 good squirts of fairy liquid,then run engine for a week and change the oil again,use a cheap diesel /petrol oil from the supermarket ,not that fancy rip off synthetic long life ****.change oil every 6000 miles with a oil filter every third oil change

Jeep 2005 liberty. When I drive my jeep more than 30 miles lots of smoke and burning smell come out. The weird thing is that the oil meter is not indicating it is hot.


Hello....

Sounds like you might have a blown valve cover gasket. That is were I recommend you to start checking. If that is good, check for a leak around the intake manifold.

Good Luck...

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.

Jeep 2005 Liberty CRD diesel oil light and beep


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.

Jeep chocks, stalls, rpms shoot up n down n dies


Check fuel pump for pressure and output. If it's not that, don't start guessing... have a scanner put on it and get some codes. While some codes can be ambiguous, it will serve to start you in the right direction!
