Jeep - Suspension - Grandcherokee :: 2004 - Ambient (outside) Temp Sensor
The ambient (outside) temperature sensor on my 04 jeep grand cherokee is now stuck in the open position (it reads -40 constantly) after having body work done to it. Could this be a fuse, loose wires, or is the senor broken? Also could this have been damaged by the body shop?

My '01 Grand Cherokee Limited is overheating. I have changed the thermostat and ran a leak test. I am not having a leak. The temp drops when I turn on the A/C or heater. I went back to the shop that changed the thermostat and leak test. They said it was the fan control and I have to go to the dealer to reflash the program for the fan control. I made the mistake of asking the dealer to reflash, instead of having them check on the overheating problem. I'm planning on going back to the dealer to have them diagnose the issue.

I inherited a 2008 Jeep Grand Cherokee from my late father and it seems like whenever the temperature overnight drops below a certain level, in the morning the low tire pressure light pops on. I never encountered this problem with any other car I owned, is this something inherent to SUV's with all wheel drive?
View 7 RepliesJeep - Grandcherokee :: 2002 - Slips In Transmission
I was experiencing a slight slip in the transmission first thing in the morning when the temps were below 60 degrees in my 2002 Jeep Grand Cherokee (42RE). Per recommendations of many of the regulars on this forum to combat such an issue, I added a can of Berryman's B-12 Chemtool to the fluid. I drove it a couple times and everything seemed fine. It sat for a week or so, went to drive it tonight, and now the check engine light has come on and the transmission is slipping badly.
I don't know if they have changed anything with that stuff or what, but I just wanted to give a heads up that this may not be such a hot idea anymore, for whatever reason. I will try changing the filter and top up with some fresh ATF+4 (and probably drain and refill a few times) and hope for the best. I don't have a code reader right now, so I can't pull the codes and don't want to drive it to the auto parts store the way it is now, but am pretty sure they are related to the slip.
Jeep - Grandcherokee :: Auto Transmission Won't Get Out Of 1st Gear - RPMs Can't Exceed About 29 Mph
2002 grand cherokee... Just took her in on Friday to have valve cover and oil pan leaks fixed, and within an hour of picking it up today the automatic transmission won't get out of 1st gear… rpms rising and can't exceed about 29 mph. Straight 6 engine. Any chance the mechanic messed something up, like a throttle cable or something, or is this just terrible karma?

I have a V6 Automatic 2001 Jeep Grand Cherokee with 94k miles on it. For the last two years my transmission has been slipping only when I make left turns. I have tried changing fluid and filters. The problem hasn't gotten worse but it is pretty dangerous as I cannot accelerate when I make a left turn. I was wondering if there is anything that could be causing this problem.

01 Jeep Grand Cherokee. I just changed the water pump and the thermostat on the Jeep but the last two days when I drove it to work, the heater was blowing cold air and the engine was getting hot, almost to the red. What do you think that I should look into about getting the problem fixed>?
View 6 RepliesJeep - Grandcherokee :: Engine Occasionally Shutting Off When Car Is Idle
I have a Jeep Grand Cherokee 2001 with about 150,000 miles. About every other day my car will shut off while I'm stopped at a light, stop sign, etc. The strange thing is that the radio and lights (stuff controlled by the battery I assume) does not turn off with the engine. It seems the frequency with which this happens has stayed about the same, and I haven't been too worried until yesterday when I went to start my car and it would not start. It just kept revving and seemed like it was very close to starting.
I opened the hood and saw a lot of corrosion on the battery and luckily I had a coke in the car. After pouring some coke and wiping away the corrosion, the car started up. I have had no problems since I did this yesterday. But like I said, my car engine seems to turn off without warning so it could happen next time I drive. If these two problems could be linked, that is the corrosion on the battery could have caused both the car not starting and the engine shutting off when the car is idling. I took to a mechanic about a month ago and they couldn't find anything wrong with it and, of course, it didn't shut off when they drove it.
Jeep - Grandcherokee :: 2006 - Loud Engine At 65 - 70 Mph / No Torque
I have an issue with my 2006 Jeep Grand Cherokee v8 Laredo that has been bothering me for a little over a year now. When the temperature gets warm out (over 80) and I am traveling on the interstate up a long hill (65-70 mph, towards the end of my commute so about 30 miles in or about 30 minutes) my engine randomly begins to sound like I am in the wrong gear (RPMs do not change but engine sounds like I just changed to second) and I loose quite a bit of torque. I can maintain my speed but my engine sound horrible. After about 10 minutes of this my engine goes back to normal and I can accelerate without issue. Then randomly it goes back to being loud with low torque. To add to the the fun, if this happens at any time during the day, the next day when I start my Jeep the issue resurfaces and I have no torque for about 10 minutes (5 miles) then all is well for the rest of my commute (40 miles downhill). I had a diagnostic scan done and they found nothing wrong and I also just got both of my exhaust manifolds replaces but the issue continues.

I have a 2005 Jeep Grand Cherokee with 120,000 miles. The engine light came on and I took it in for service. The catalytic converter was defective and replaced. After service and 30 miles the light came back on. They erased the memory. After 35 miles the light came back on. So far I have returned 4 times and they cannot find the problem.
View 6 RepliesJeep - Grandcherokee :: Engine Sounds Like Its Turning 4000 RPM But Only When Cold
My Jeep sounds like it is in low gear and engine sounds like its turning 4000rpm but only when cold. This is so noticeable that dogs stare and pedestrians run for cover. Once the engine and drivetrain warm up a little, all is normal. The reality is that the engine is only turning 2500rpm and it is shifting, but the tranny doesn't feel like its grabbing very well. After just a few minutes driving, all is well and there is plenty of power. Fluids are all topped off and fresh.Is it time to warm this baby up and drive it to the nearest car lot?
View 5 RepliesJeep - Grandcherokee :: Engine Occasionally Run Rough At Idle / Low Rpm Before Stalling
I've got a 1998 Jeep Grand Cherokee, 6 cyl. engine, ~145k miles. A few weeks ago, I noticed the engine would occasionally run rough at idle, dropping down to a low rpm (~500 rpm, but erratic) for a few seconds before stalling. This usually happens when in park or stopped at a stoplight, but it's occasionally happened at low speed while coasting to a stop (never while accelerating, or while traveling above 20 mph or so). Generally, the car will restart right away, though sometimes I have wait a few seconds to a minute (I was a real popular guy at that intersection).
At first, no codes came up, so I changed the plugs and wires (I was due anyway). That didn't work. (The plugs, while worn, looked normal to me-no residue). I've since had a P0351 code pop up. Before I throw parts at this code (ignition coil, I believe), is there anything else I should be looking into?

Honda - Grandcherokee :: Check Engine Gas Cap Code On 2001 Jeep
My daughter's Jeep check engine light is on. Trying to get the car inspected so cannot be ignored. I think the code wasP0422, indicating it needed a new gas cap. We bought a new gas cap, cleared the code and it went away for a few days but before she could get it inspected, the light came on again. I saw similar problems suggestions were to get a better gas cap (we got one at autozone), or it could be something like a pump problem. We haven't taken to a dealer - it's a 2001
View 17 RepliesJeep - Grandcherokee :: 1994 - Check Engine Light And O2 Sensor Malfunction
So this little gem of an SUV has been good enough to me over the year that I have had it, but it is one of those used vehicles that has me scared to look underneath cause there is always something a miss.
I have been having some power problems and the OBD check engine light has been coming on. The engine like to putter like if it's not getting enough fuel from a clogged fuel filter when it gets going, hot or cold. Have confirmed that the fuel pump is with proper voltage and pressure. Though haven't noticed a big difference with the new filter. The check engine light cycles a code of 21, which is refinanced to the O2 sensor, both upstream and down stream. That tells me that there are TWO O2 sensors for this model. And research has confirmed this. One ahead of the cat and one behind the cat.
Here's the kicker, I only have one O2 sensor at the head of the cat and the location of where the second one would be located is only a solid section of pipe from cat to muffler. I haven't been able to track down the plug connection for the second sensor and these codes and problem only came after I gave the Jeep a tune up.

Jeep - Grandcherokee :: Distinct Clapping Noise When Engine Is Not Up To Operating Temperature
I noticed that my Jeep has been making a distinct clapping noise any time the engine is not up to operating temperature. It sounds worst on cold mornings, but becomes quieter as the engine warms up. The noise is RPM dependent, so I'm assuming it has something to do with the engine. The noise is not audible when the engine is idling in park, but quickly shows up as soon as I put the car in gear and add gas. My father and I think that a slightly loose rocker might be the cause of the noise, but we're not sure. A mechanic friend of his told him that our jeep has self adjusting rockers so it can't really be fixed without replacing it. I've never heard of such a thing so I'm having a hard time believing it. The really confusing part is that it only makes noise when the car is in gear and the engine is under stress, making no noise when it's just idling, even when the engine is revved. Since purchasing it 5 years ago, we have been careful to do regular maintenance on our jeep so I'm somewhat surprised by it.

Jeep - Grandcherokee :: 1999 - Engine Stalls For 5 - 10 Seconds And Fires Back Up When Driving On Highway
My 99 jeep grand Cherokee 4.7 v8 4x4 will not start after 2 to 3 short trips. it starts up fine in the morning when the engine is cold but driving for a while while and I stop somewhere and shut the engine down for a few minutes it will not restart.. after I wait 10 to 15 min it start up ok.. Next when I'm driving on the highway, after 10-20 mins of driving, the engine stalls for 5-10 secs. and fires back up..I inspected all connections and the starter which were ok but I did find that the starter is soaked with oil dripping from the valve covers.. Could the oil be the problem..? Even causing the stalling out on the highway..?
