First thing I should say is I have never reset an oil guage so I have no idea. Ok, close to the oil filter their is a wire that plugs into the sending unit. Whenever I change the oil I always unplug that wire so its not in my way when removing or installing the filter. Let me know if that helps.

I would start by obtaining a new oil pressure sender unit at autozone or advance. These are screw out and screw in with a deep well socket easy install once you find the location. I would suspect the sender going awry before the gauge and the doing anything with the gauge will involve taking dashboard apart.

What to check when oil pressure gauge flucuates while driving a jeep cherokee


To verify there is a problem, remove the oil pressure sending unit, replace it with a test gauge, start the car, idle, accelerate etc and watch the gauge for any abnormal variations it should react to evry change in acceleration and not be below the minimum or above the max as per the service specs.

Recently bought a jeep grand cherokee laredo 1994, it had been sitting for a year or so. When we got it started it is tapping a little, smoking alot, and gauge is showing zero oil pressure. I'm af


If it is a 4.0 strait six cylinder this is a common problem on them.Mine was located just below the oil filter and is pretty easy to fix.Plan it on your next oil change and it is even easier to change out.Oh just so you know your 4.0 liter engines do make a little bit of noise but are pretty much bulletproof if you just do regular maintence on them.Next time you start it put your ear down by the driver side hood hinge.You will find some tapping noise there it is part of the evap system.If it had no oil pressure you would know it rite away.

My oil pressure gauge goes to the H


Not really , when you give it gas it creates higher pil pressure at higher engine speeds, when the engine slows down there is less pressure on the oil.

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.

The oil pressure gauge keeps dropping down to 0 while i am driving


If you don't hear any ticking or knocking while the pressure gauge drops, the problem is probably a failing "oil pressure sensor". If you do hear a ticking or knocking, the problem is probably a failing "oil pump".
