Jeep - Cherokee :: 1995 - Oil Pressure Gauge Pegged
Jul 18, 2012
95 jeep cherokee. My oil pressure gauge sometimes jumps up to 80lbs or bobs between 40 and 80lbs. Could this be anything other than sensor or gauge itself?

View 12 RepliesThe Oil Gauge on the Instrument panel of my '99 Jeep Cherokee Classic is pegged fully to the right (TWICE the normal reading) when the vehicle is Stopped at a Light or stop sign. As I accelerate the needle drops down to NEARLY normal but pegs again as I decelerate to a stop. The engine sounds normal, operates like normal, no smells, oil level on dipstick is OK. What's up with this?

The oil pressure usually runs around 1/8-1/4 when driving around town and now I am getting temperature spikes. I had the coolant and water pump replaced last fall when I was having similar idling issues then. My coolant isn't a perfect green color--it is a little bit grey, but it is full. I cleaned the entire throttle body last January, cleaned the IAC today, and redid the NSS this week (not that this probably matters, just being thorough in my explanation).
It seems to happen worst on hot days (of course) when idling in traffic for a few minutes and makes the air conditioned air run warmer than it should.
Is this a busted radiator? The mechanic said I did not have a leak when I had him check last week.
I have a 1999 Jeep Cherokee Sport with 140K + and recently had an oil change. I went on a 8 hr road trip split up between 2 days (there and back). On the way home I noticed my oil pressure gauge acting funny, going up and down but not past 40. Today, I drove home from work (10 miles or so) and the check engine light came on and the oil pressure gauge was very low, almost 0. I made it home but was very nervous and noticed both today and this weekend there was smell, burning or burned type smell. What should I do? I don't really trust the garage that changed the oil and was skeptical taking it there but was in a pinch.
View 12 RepliesSo I have an 88 k1500 with the 350 that the previous owner removed and rebuilt... Didn't hook a lot of stuff back up etc... It's like a puzzle. It runs good for the most part but the oil pressure gauge in the cab pegs out when it's running. I've heard 1989 and older 350 engines have 2 oil pressure switches/sending units. I know about the one up by the distributor. But can't seem to locate the other one. Also what does the one by the distributor control? And what does the other one control?
View 1 Replies'95 Jeep Grand Cherokee Laredo 4x4 (bought used 3 years ago), The Jeep sometimes dies while we are driving it. Most of the time we can restart it right away, but others it will make the turning over sound and not "catch" & go vroom.
Other times we'll be driving down the freeway (for example) and it will do a little shutter, like it's going to die and if we push on the gas it kinda skips over the dying part.
We thought it was the fuel pump, so my father-in-law took it to a mechanic and he checked it out and said the fuel pump is fine. His assistant drove it around for a while & it never died on the (of course). So he said it was fine and suggested we got some bad fuel and told us to put in some Chevron, but later that night we drove it close to home for 20min & it worked just fine. Ate some dinner at Mom & Dad's then it wouldn't start up again.
We've changed the Fuel Filter, it has a new Radiator, New Brakes and Just got an Oil Change, we filled it up with Regular Chevron and added 'HEAT' (additive to get rid of moisture)... We are at a loss...
My manual transmission 1995 Jeep Cherokee today refused to go into any gear after I had stopped for a light. After pushing it to the side of the road I was about to call AAA when it went into gear and worked perfectly thereafter. This happened once before about a month ago. What could be the problem and how likely am I to get stuck for good?
View 5 RepliesI have a 95 Jeep Cherokee that has a strange electrical problem. When I first turn the car on after it has been sitting for several hours, the following accessories do not work:- Air conditioner/Ventilation- Wipers- Cigarette lighter
There are two really odd things going on here: The first is that the radio will not work if any of the above three things are turned on, but it WILL work if they are all turned off. For example, with the wipers and AC off, and cell charger unplugged from the lighter, the radio will turn on. As soon as I plug the charger in, or turn on the wipers or AC, the radio goes off. None of these accessories actually turn on, but simply being putting them in the "on" position kills the radio until they are switched off.
The second weird thing is that after a few minutes of driving, everything will return to working as normal - radio, AC, lighter, etc. They continue to work until the next time the car has been sitting for several hours, at which point the same problem repeats.
FYI, I recently replaced the alternator to address an unrelated issue, but it did not make a difference with this one.
I searched the car talk forums for similar issues, but did not have any luck - while it does look like there are some other Chrysler vehicles that have electrical problems, I couldn't find anything dealing with an intermittent problem.
My father has a 1995 Jeep grand Cherokee that drains the battery every few days. I draw tested the battery and it is fine. The alternator is charging fine. During a check of the circuits for battery drain, I found that the MUX/T Tow 50 amp fuse is draining the battery at a rate of about 1.5 amps or more. The manual I have does not list the fuse so the following questions come to mind.
1. What circuits are on this fuse?
2. Can the truck be safely operated without this circuit?
3. What further can you do to detect the trouble?
Some answers I came up with after a little more checking.
1. The gage cluster does not work when the fuse is removed, it must be on this fuse. None of the cluster system lights come on when this fuse is out. The cluster illumination lights work ok.
2. All external lights work without the fuse in except stop lights.
3. All other functions are working without the fuse in.
4. No the truck cannot be safely operated. See answer #1and 2 above
5. Found online that a check of any trouble codes might determine touble.
6. No codes were found. But i ddid have the battery cables off before this was checked. He is going to drive it home and back on Sat so I can recheck the codes.
7. Many replys to other posts here on this site refer to the MUX as a "multiplexer"
More questions
1. What the heck is a multiplexer?
2. What relay controls the cluster? Or is this done directly by the ECM.
I do have a good background in electrical and electronic circuits of many types, mostly radio and computer, but also including automotive. So feel free to beat me up if I am overlooking the obvious. I just feell like I am beating my head against the wall here. AND this is what it feels like (thought that was real cute)
I have a 1995 jeep Cherokee country that has 130k miles. I have notice that when I shift from park to drive, park to reverse, drive to reverse or vice versa It makes this thud noise after placing it in gear. Is this a sign that the transmission is about to go out ? What action should I take? By the way its a automatic transmission
View 1 RepliesFor the first ten minutes after my car is started (until it warms up), the oil gauge drops to 0 while accelerating. When I take my foot off the gas, it goes back up. After the car is warm, the gauge works fine and unless the car cools completely down, it gives me no more trouble until the next morning. We have tried:
1. Changing the sending unit (twice);
2. Changing the oil;
3. Working on the electrical contacts;
4. Cleaning all of the parts around it.
I have a 95 jeep Cherokee and have lost all power to my radio, heater, wipers and turn signals, i have checked all fuses and replace a relay i thought may have been bad, I have yet to find any inline fuses that may cause the issue.
View 1 RepliesMy '95 Grand Cherokee (104K miles) just started groaning when I make full turns. After first 1 or two turns, right or left, can hear the steering column groan and feel some resistance. Have I lost power steering fluid? or worse?
View 2 RepliesI purchased a 1990 Jeep Cherokee Laredo at a steal . . . I've already replaced the head gasket sealant. My biggest current concern is the fuel pressure. The car either starts up beautifully or sputters and gurgles for a good 5 seconds before finally idling normally (either occur during cold or warm starts).
The sputtering at start-up has become more commonplace as of late. If I drive away without providing a good three-to-five minute warm-up, the car will drive as normal while applying gas pressure to the peddle, then once gas pressure is no longer applied, the car dies silently; The battery stays on, but all power steering and engine power disappear and the car coast into nothingness. If I allow the Jeep to warm up significantly, it will drive as normal for hours, except for it's struggles to compensate long upward hills.
The fuel regulator has a slight leak. Worse at start-up, lessens up over time. The seal may be improperly seated, but is in physical working condition as I can tell. Spark plugs were replaced. Battery was replaced. Injectors have been tightened. There is a slight oil leak (it seems to move around a bit), but is far better since the Head Gasket was replaced. Could this be a bad fuel regulator or something else that I have missed?
I'm looking to trade my '95 dodge ram 1500 with someone for their '95 grand cherokee. The GC has 190k miles on it, my truck has 155k.
I noticed when test driving the GC that the oil gauge follows the rpms of the engine. I.e. when idle the oil gauge is low-mid level. When i raise the RPMs, the gauge indicates there is more oil pumping, then when i go back to idle it drops back down too; in other words it looks like the oil jumps with RPMs.
I've never seen this type of behavior before, is this a sign of typical behavior for a jeep GC, a bad gauge, maybe an oil leak?
My oil pressure gauge jumps all over the place when I get over 3000 rpms. At lower rpms it is in the normal range and the engine sounds ok. How can I tell if this is the oil pump or the sending unit or the gauge? This is a 1980 CJ5 with a 151ci 4 cylinder.

Sometimes this vehicle only starts when hot
Some times only when it cold
I have recently fixed the fuel leak.
When its hot or cold and not starting if i relieve the fuel pressure at the fuel rail, in most cases it will start immediately. However if fuel pressure relief does not work. I disconnect the vacuum line at the what looks to be the EGR valve or the pressure regulator at the front end of the rail, then usually starts right away.
I have not tested at this time to see if the fuel pump is failing nor have i tested fuel pressure. I am trying to narrow down the problem to one specific part. There is no problems with cranking. There is spark - coil, plug, dist cap have been replaced.
It seems the problem is with fuel delivery of sorts. It was mentioned that sometimes the heat from the engine could be heating the fuel rail to a point which turns the fuel into a gas not allowing it to atomize.
Gauge/Sensor Problem ??? Great oil pressure on start up (40-60 PSI) but as car heats up, gauge SAYS pressure is dropping below 20 PSI. Dip stick says plenty of oil and filter is brand new. No knocking from valves either.

I was driving home with a known overheating problem, when the temp gauge pegged and a heard a distinct rattling. I knew right away what happened. as I pulled over the engine stopped turning. I opened up the hood, and my suspicions were confirmed. I blew a headgasket. I went back into the car to call AAA, and I heard a loud POP!! the radiator blew from the heat and pressure.
after it got home and cooled down I tried cranking it over and it has NO comression. it just spins.
should I take the time and money to replace the headgasket, or should I just get a junkyard motor?
I know I need a new MAF. I had a "multiplicative fuel system running lean" code for a LONG time. I regrettably assume this is what caused the failure in the first place.
So a couple weeks back I'm on expressway home and I look down and and temp gauge is pegged out overheating I immediately pulled off and shut it down and towed to a buddy of mine's shop he flushed it filled it up w antifreeze and checked for leaks and couldn't find one. I drove it for about a week and got out to for a quick stop , Ex parked on a slight decline and came out to prolly half gallon of coolant on the ground..I limped it to my buddies shop as it was not running hot .. he has checked it out but can't find any leaks, even after having it run 30 or so minutes..
View 6 RepliesYesterday my fuel gauge stopped working it is pegged all the way to the left. I filled up the truck no change. Got home and my garage door opener would not work and when sitting in car the map lights wont come on, the overhead lights work when you open the door. Cannot find any reference to what fuse any those items are connected to. is there a fuse for the fuel gauge?
