2001 Jeep Grand Cherokee Questions & Answers
How do I complete the computer diagnostics drive
alot of times when the monitors dont set its because you may have a defective coolant temp sensor or air temp sensor. Some monitors will not run if the sensors never get between 10 degrees of each other and both being under 160 degrees.
The way to check is to use a data scanner. After sitting overnight they should both be about the same temp. Or if you have a data scanner you can force the temp by heating or iceing them to get the desired results before starting the vehicle.
If you dont look at the data before you start the car you will never know if thier faulty
2001 Jeep Grand Cherokee. My Jeep is overheating and when I shut it off the reservoir is bubbling a lot like coolant not going anywhere. What would that mean?
If your Jeep is overheating and the coolant reservoir is bubbling, it could indicate that there is an issue with the cooling system. Here are a few possible causes:
- The radiator cap is faulty: The radiator cap is responsible for maintaining the proper pressure in the cooling system. If it is not functioning properly, it could cause the coolant to boil and create bubbles in the reservoir.
- The water pump is not working: The water pump circulates the coolant throughout the engine. If it is not working properly, the coolant may not be circulating as it should, which could cause the engine to overheat.
- The thermostat is stuck: The thermostat is responsible for regulating the flow of coolant into the engine. If it is stuck in the closed position, it could restrict the flow of coolant and cause the engine to overheat.
- There is a leak in the cooling system: If there is a leak in the cooling system, the coolant level in the reservoir may be low, which could cause the engine to overheat.
It is important to address any issues with the cooling system as soon as possible, as an overheating engine can cause serious damage. You may want to take your Jeep to a mechanic for further diagnosis and repair.
Where is the ac drain
for sure all generic answers here are wrong. for all grand Cherokees. 93 to 2010
posters jeep is 2001 WJ , only WJ 1999- to 2004 (USA only) are correct. RHD cars are not the same. UK
we all know why, (clogs happen evap drain clogged)
we all know it must be cleaned. (just like clogged kitchen drain )_
what is not told , "your hands can not reach the spot. transmission block you, and CATs)
the drain tube on my 2008 wrangler(2dr) is in plane site just above starter. so is easy
the wJ and WK jeeps are not easy, and WK is the hardest of all made. blocking shield under car.(above right side of transmission NAG1.
THE FSM LIEs IS HERE. Jeep sells the cleaner kit and the TSB covers how in 24 long pages.
but step 1 below fails; (way to go JEEP,. FCA) #2 is CAT crossover,3.7L
ABS light on a 1999 jeep grand cherokee
Hi Amalia:The ABS warning light comes on when there is a fault in the ABS System. When the light is on the ABS System is not working. A diagnostic scanner computer would be required to pull the trouble code and to diagnose the failed component would need to be repaired or replaced to get the light to go out.Hope this helps; also keep in mind that your
feedback is important and I`ll appreciate your time and consideration if
you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.
2001 4.7l diesel. Does it have a limited slip differential?
4wd or NOT, 2wd, but 4wd both ends match.
well , not wanting to pulled cover off and have GL5 lube all over
or #2 googling for all Jeep axle codes. (your call)
there is no CHEVY RPO code build list\
#3you call jeep dealer give VIN and he tells build list to you.
or the tests. #4
put car in 2wd, but one rear tire on ICE or wet grass
then move forward quick. (gas pedal
if both tires spin car moves is Positration clutch packed rear gear set.(or lockers of many kinds)
if limited slip 4 gears only then one tire on grass /ice only spins fast and car does not.
there answered all 4 ways.
ok way #5, rear tires off ground both, ON JACKS STAnds safe.
in neutral 4wd box or. if not 4wd tranny in neutral.
hand spin 1 tire and both turn same direction for locker.
if it 1 spins backwards the axle is open (limited slip)
open is 4 gears (side+ spider)
Lockers have a locker or clutch pack just like seen in the A./T BOX.
lockers have vast names. but all lock up some way.
open axles means sans/locks.
I love lockers. saved my bacon vast times. even pulling super heavy boats out of the ramp, and zero slip. 2 tires spin is JOY.
even 2wd drive with a locker is a joy. on snow and ice too.
1 wheel drive is for squids.

2001 Jeep Grand Cherokee. What is this clicking noise?
Question edited for clarity. Please don't use abbreviations, and please put 'year make model' as the first three works. The other benefit is that the site scripting will put you in the correct model category. I moved it for you. :>D
This noise is likely to be the Universal Joints on the drive shafts. They are covered in rubber boots, the boots split and that lets in water and road grit which in time causes wear.
Take it in for diagnostics.
2001 Jeep Cherokee XJ - won't shift?
Your dealership is spinning you a year to get you to pay for a new transmission. Tell you husband to get back underneath and look for pulled or damaged wires from the bumper job.
Or call a transmission specialist. This is an electrical fault.
Jeep 2001 jeep grand cherokee v8 4x4 Laredo code p1686 code showing up...
Hey There...I am not a Mechanic and cannot answer all your questions, but I did not see in your statement where you disabled or removed the skim (Sentry key immobilizer module) prior to installing the new PCM. Even if you have the Skim de-programmed in the PCM, you must unplug or preferably remove the skim or it will immediately reset the PCM when you connect it to the car. The skim is the module under the steering column with the little halo that that goes around the ignition. If you did not disable the skim you will have to have the PCM deprogrammed again. If none of this helps, I apologize. I am just learning about all this myself.
Brake pedal got hard now
skdavisbob, This sounds like you have a problem with the brake booster that is attached to the firewall. When these boosters fail it is like trying to stop a house as you describe here. There is a one way check valve near the top of the booster that uses vacuum from the engine to operate. Inspect the hose and be sure that it is attached at both ends and that there are no leaks in this hose. This can be done by running the engine and listening for a leak. (hissing noise) Replace the hose if faulty. If you don't hear any vacuum leak then turn the engine off and pull the check valve out of the booster. This takes a little effort as it is quite secure in the grommet. You should hear a vacuum leak for a split second because when the valve is removed it will allow air in (if it is working properly) and you should hear the leak. If you don't hear the hiss, then test the valve by blowing through it both ways. As stated, this is a one way valve and you should be able to blow air through one way but not the other. If you can blow air both ways then the check valve is faulty. If the hose and valve are working properly then you will have to have the booster replaced. Good luck with this.
Error code p1686
either the chip in the key is bad (try the other key) or the receiver on the back of the ignition is bad. If both keys dont work there is nothing you can do but have it towed to the dealer.They have to replace and reprogram the unit and the keys! I am sorry.
Heated seats are not working but light is on
Sounds like the same problem I had. I brought it to the Jeep dealer and they told me that the heating element in the seat stopped working. They told me that the only way to repair was to take the seat apart and replace the heating element in the seat. Of course they will charge you the standard $80 to tell you this. and then quote you $500 plus to repair. I can't even remember how much, I have decided it was not worth it.

Your catalytic converter is not doing it's job efficiently enough and it is setting off your sensor. This problem is emissions problem and usually has no effect on the operation of your vehicle( unless the converter clogs) As long as you don't live somewhere they do emissions test you don't really have to worry about it. However if you want to fix it you can take converter off and run a straight pipe or to do it "right" you could go pay way to much to get a new converter put on.

The OBDll system will need to be reset with a scanner. Waiting for the computer to do a system can take time and mileage.
