Question about 2001 Jeep Grand Cherokee

Oil pressure drops to 0 in 2001 Jeep Grand Cherokee Laredo

The oil pressure drops to 0 when we are slowing down. It moves up as we accelerate. I was almost certain it was the oil pressure switched and replaced it. The oil level is fine, I have checked regularly since this started happening. I was wondering what else it could be, or if I am missing a step in the replacement of the sensor. Did I need to reset it after installing? Any help would be great.

Does it act different when this happens???? If not do not worry about it. It is just the Oil Pump slowing down with the Motor and will not hurt anything. My 600 HP 95' Silverado does the Same thing and it is not a Problem

    That is a Safety Chirp on the Jeeps. It is REALLY annoying, I know. My Dad has one Also.You might need to Change the Oil Pump But, I would have a Diagnostics ran on it by a Qualifird Tech and see if there is an Easier Fix than that First!

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.

I have an '01/'02 Grand Cherokee Laradeo, when I slow down the oil pressure drops to zero, when I accelerate it goes back up. There is a quiet knock as well, this just started happening. Pleas


If there was no noise when it went to zero I would replace the sending unit by the oil filter for a few dollars. If it is a light ticking and it is all the time I would replace the bad lifter but if it is more clanking or thumping you have problems. If you disconnect one plug wire at a time and run it for a few seconds and the noise goes away that cylinder has a bad connecting rod bearing. I would pull the oil pan and replace the bearing. Or just replace crank and connecting rod bearings and get rid of it

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.

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

2001 Jeep Oil Pressure


Last week my 2001 Grand Cherokee with a 4.7 was dropping below 10 and my "check gauges" light and chime came on. My sending unit was bad. I could see it was bad because oil was getting through the unit and leaking very slow. It's located above the oil filter. Easy fix, but the unit was over $50 and the 1 1/16 special deep socket for sending units was over $10.

High engine oil presure


Hi, I had the same problem, same vehicle (same year), same engine. I bought an oil pressure tester at Harbor freight tools for $ 8. I was trying to figure out, if the pressure is really high, or just the sending unit is defective. The tester after connecting it to my engine was reading correct pressure for this vehicle ( between 25-30 PSI when idelling), which showed that the oil pressure sending unit is defective. At Advanced autopart store they want about $ 47 for the sending unit, so I put the defective one back in place (still reading H). I'm planning to replace it after next pay check :o) Good luck.
