OIL pressure light switches are one of the things that leak as they have a metal base and a black plastic insert and when over a while the switch gets hot same as the engine and the rubber gasket between the plastic and the metal base starts to leak .
So what you do is to wash down the switch area with a drop of petrol then let it dry for 10 minutes before starting the engine and watch the leak it might take 10 minutes as the oil has to get hot /and if it leaks when cold then replace it NOW
Let me know how you get on.

ENGINES ARE A BIG PRICE for the price of a switch RON

Lots of oil leaking under the Jeep. Down to no oil right now. Rainbow trail, etc. Want to know worst case scenario...ballpark cost to fix, etc.


Could be a simple fix. Have you found where the oil is leaking from? I had a 93 Grand Cherokee that was leaking oil badly and I found it to be the oil pressure switch that was leaking all that oil. It only cost a few dollars to fix. Check exactly what is leaking first to determine what it will cost.

Oil pouring out


Depends where the oil is flowing out from. Usually, on the Grand Cherokee, it's the oil pressure switch that leaks oil. It's right next to the oil filter. Have it checked out.

My 1997 Jeep Grand Cherokee cuts off while I'm driving.


If you have zero oil pressure thats a BAD sign, first have a mechanic check what the engines actual oil pressures are.

Oil leak, 5 quarts in 75 miles. Somewhere to the rear of the filter, filter OK


Hello thundergod: My name is Roger and I will answer your question.Their is a oil pressure switch located to the rear of the oil filter. Should have a shield over the terminal. When this switch ruptures you will have a large oil leak. If you unplug the switch and start the engine you will see the switch leak. If you have a gauge it is called a sender unit. If you have a light on the dash it is called a pressure switch. Please rate the quality of this answer as this is how we know you received the right answer. Thank You for using FixYa.Roger

Oil pressure gauge on my 2000 jeep is on


The most common problem is a bad oil pressure switch on the 99-02 grand cherokee with the 4.7l v8. The part has failed on 90% of all 99-02 grand cherokees I have worked on. The housing is junk,but since it has lasted longer then 36,000 miles the factory would not issue a recall. The oil pressure switch can be purchased at any outlet. but have found the duralast was decent. that being said Go to autozone and get part # PS471 (oil pressure switch for 1999-2002 N code 4.7L V8.) chances are if you encounter the same problem after replacement you will need to drop the oil pan and un clog the oil sump.

To replace the switch, under the hood look for the power steering pump on the driver side of the vehicle, to the right and under the p/s pump is the oil pressure switch, If it is wet, its bad for sure, remember to disconnect the battery before service,as not to harm the gauges.

01 grand cherokee fan relay/oil pressure


I don't know if this will help anyone, but i had a issue with my jeep running hot and check engine light coming on as well. After alot of trips to different shops - the last one found that there were two senors in the engine for the fan that need to be changed. Everyone would aways fine the one up top but not the second one. After that, have not had any other problems like it since.
