Low oil pressure light only comes on when I am

Low oil pressure light on my 2002 Jeep Liebrty only comes on when I am idling? As soon as I drive, it goes off. Should I try replacing the sensor first or is my oil pump going out and if so is it safe to drive?

First thing to do is to make sure you are using the correct weight oil for your vehicle which is 5w30. Make sure you are using a quality filter such as Mopar, Purolator, or Wix. If that is the case then replace the oil pressure sensor. If the problem is still there have an oil pressure test run on the system. If the oil pressure is low at idle then you will need to remove the oil pan and find out why. Could be the oil pump screen is clogged or the oil pump needs replacing. You need to stop driving this vehicle until this problem is solved or serious engine damage could occur.

Well what type of oil are you using and filter i would try changing oil to good grade oil and get good filter like fram or something good not cheep try this if that dose not fix you can try new sensor or get a gauge from the auto store you can rent and have them give you the spec for oil psi and check it with gauge and see if psi is in spec this will take the guessing game out it could be bad pump but we have not seen this in are shop we do lot of jeeps hope this helps

Was the oil pressure checked under a load when the car was accelerating if idle oil pressure was good but lower when the vehicle was under a load it could indicate a partial blockage of the oil pump screen and a posting of the oil pressure numbers would be helpful if you are satisfied with the numbers and the test was done properly and the switch replaced you have a problem with the circuit

Have a reputable garage check the oil pressure with a manual oil pressure gauge. Very well may have worn internal parts, or weak oil pump. Thats the only way to know for sure.

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.

97 wrangler oil pressure drops when engine is at idle


check the engine oil level... you could possibly need to replace the oil pump soon... if you do not live in a cold climate i would consider using 30 or 50 weight oil. do NOT use that in a cold climate as the oil is like molasses when it gets cold.
that's only temporary. one other thing to consider is a clogged oil filter... when was the last time it was changed ?
