This guy has a good article on how to replace the crank shaft position sensor and why it does what it does. I have a 2000 Jeep Cherokee and it's doing the same thing to me right now. My local auto repair shop can't get it to code on the computer when they try to recreate the problem. It's so sporadic. It's driving me nuts. The shop guys are afraid to replace a part that they don't know for sure is bad, but I'm 99% sure this is what it is. I told him to replace it anyway. He looked at me like I'm stupid. Probably because I'm female. LOL My advice, don't be a jerk.

I have a Jeep Grand Cherokee limited edition year 2000. I love this vehicle but lately it has been worrying me because on one particularly hot day, 90 degrees, I was driving along over and overpass and suddenly everything just died with no warning. I pulled over safely and noticed my gauges were not working. after 10minutes or so, the gas gauge suddenly came to life on one of my many attempts at starting and it started up quickly. it happened again that very same day and I was stuck on the side of the road with hood up and after 10 min or so, same thing, gas gauge came to life and it quickly started. I have read all the posts I there are some similarities but I am unsure on what to change first. the PCM? any help would be greatly appreciated. 2000 jeep grand cherokee limited V8 4.7 liter. 2wd. 140,000 miles.
thank you

My 2001 Jeep Grand Cherokee was stalling out while driving and the odometer code read P0320 which means the crackshaft position sensor was bad. It is a hard part to get to but with the right tools not so bad to fix. Cost me about $70 to replace and resolved my issue. To check the odometer code turn the ignition to on then off 3x and on the third time leave on and wait for the code to display.
James, thank you so much for sharing how to get the odometer code. My 2001 Jeep Grand Cherokee is doing the exact same thing and the code is the same, so I will replace the same part. Thanks so much for being so kind in helping out your fellow sister on this planet. Kudos to you, have a great week!

My daughter has a problem similiar to what everyone is saying here, except that now she cannot drive the jeep at all without the heat on. Can you imagine having two small children and having to drive with the heat on in this hot weather? I found a site that said it was not the PCM at all, but the shorter screws that hold it together were causing it to do this. I am having my son in law check the problem asap. Good luck to everyone with this problem!
to all jeep owners if the jeep is shuting down after it gets a little hot say 10 or 15 min and will not restart then pour water down behind motor near transmission give it a couple min and if it starts up then u just cooled down the crank sensor thats your problem !!!!!!

I have a 2000 Jeep Grand Cherokee and it has been worrying me now for a month. Yeah, it stalled on me with no sign it was going to stall, just died, gas gauge went dead, lucky I coasted into a shopping center parking lot. I tried to start it but it just kept cranking, then on one of my tries the gas gauge came back to life and it started right away. possible (crankcase sensor) I then started researching it on the internet and allot of people have experienced the same thing. I changed my crankcase sensor, cam sensor, fan clutch because mine has been broken for awhile now but did not notice it, I also have the max cooling package which comes with the electric fan so that must have kept my vehicle out of overheating when the other one went out.
I cleaned my IAC (idle air control) valve, it was filthy, since I have made all those changes I can confidently say I have some confidence again while driving my 2000 jeep grand cherokee limited 4.7L V8. It runs like brand new since I changed my fan clutch, with both fans running the temp gauge is a steady 198 no matter what I do. before, it would always be a steady 210 + so my vehicle runs cool all the time now. I even suspected the PCM but after unseating and spraying all sensors and wiggling all the wires under the vehicle hood it has not let me down yet and I have been srutinizing every idle especially when the vehicle comes to a stop light, I keep my eye on the rpm's and it's a steady 6.5. After I changed the sensors it died at a stop light with AC on. so that's when I cleaned the IAC valve and I have been subjecting it to every situation , so far, idles great when coming to a stop with AC and heater on, no problem. I am back to loving my Jeep, Jeep Stalling Fixed for me.
Here is my list:

Crankcase sensor (died, no gas gauge, 5-10min)

cam sensor(same as crankcase sensor)

IAV valve removal, test and clean.(died when I came to a stop with AC on, held up traffic, arggghh)STRESS!!

clean PCM connection with electrical cleaner spray (pep boys)(this is to ensure the PCM is getting a solid signal from all the sensors)

Clean IAV connector with electrical spray.(spray this as well.)

I am taking a 4hour trip to las vegas next week so this will be the big test. I anticipate no problems, vehicle runs cool all the time. Will keep you all updated. rob.umagat@gmail.com

I have a 2001 Jeep Grand Cherokee Laredo 4.0 L and I was having issues with my vehicle not starting, poor Idle and stalling. It was as simple as cleaning my battery terminals! I was surprised myself but hopefully this works for someone else!

Well, I just read every post since the get go as I decided to once more attempt to fix the problem,(sound familiar). Like everyone else we need no description of the symptoms. About a year ago when it the stalling issue first appeared I did the voodo torgue screw fix of backing the torque screws a half of turn out and for some strange reason or coincedence I was stall free for a year. This may lend some credibility to the pcm swap. I bought a crank sensor as this appeared to be the main consensus and changed it only experience a non starting cherokee immediately after changing the part. It started fine about an hour later when I went back and tried again, same as before intermittent operation and holding your breath going up bridges in traffic where there is no shoulder to see refuge. I went through the wire harness inspecting for frayed or suspicious bad spots, wiggling a fuse for ignition seemed to help but it was a coincadentaly fix. I am going to pull the pcm and clean it and the idle air valve, try that and buy rebuilt pcm next I guess. Will post results, amazing there does not appear to be a definitive fix floating out on the net somewhere.

Update.

I cleaned the idle air valve, removed the pcm and tightened the torque screws down tight. I then put it back on and backed out the torque screws 1/2 turn. I have drove it for a few days, since my last post. Who knows how long the voodoo fix will work this time.

An update on my comments. Well, got back from Las Vegas with no problems. but, whilst driving here in the city in southern cal it suddenly stalled again. once with the gauges dying and the other it started back up. I bought the lifetime warranty PCM on ebay and a brand new IAC valve at pepboys, changed them both. it's been 1 month now and no problems, also, the vehicle seems to get better gas mileage and overall runs better with the PCM swap. summer is coming up which will be the real test. will keep you all informed.

I have a similar issue with my 2000 Grand Cherokee Limited. Last summer it died about two or three times but it turned back on in less than 5 mins. I drove it trough the winter with no problems, I thought the problem got solved with the tune up that was done last October. However, a couple of weeks ago I was driving it on a hot day; it died twice but the second time it wouldn't start up at all so I had to call a tow truck. I was told that it might be the Crankshaft Position Sensor. Does anyone have any ideas as to what the problem might be? I would really appreciate your help.

Had the same problem. My service manager at Goodyear tested the battery and found it to be the culprit. No problems since. Jeep copuldn't even find the problem.

My 99 Grand Cherokee is having this issue as well. The temp reads 210 (normal range) then creeps up just slightly. Once it creeps up even a needle width past 210 there is a good chance that everything will just shot down. I have been told it is one of 3 things: The Cam sensor, the Crank Shaft sensor or the PCM. I have replaced both the CAM and Crank shaft (the cheaper parts). Still having the problem. I'm actually going to try resetting the PCM and see if that works. If not I'll order a new one refurb from auto zone - $260 (about $500 cheaper than retail).

Disconnect the battery for an hour to hard reset your Jeep's brain. Sounds offbeat - but have read folks who've done it and it has fixed their problem.

Failing that turn on and off your ignition 3 times - leaaving it on the last time. If you see the code p0320 displayed in your odometer you need to repalce the crank sensor ( which you can by on ebay and install yourself ).

We have a 2000 grand cherokee with 95000 miles and we've been having this problem for several weeks. The dealer kept it for a week and couldn't find the problem...it showed no codes. On another forum (CNET Forums: Car Tech)there were posts about mid-90s models having this problem and it possibly being a PCM issue. My husband tried the fix but the configuration is a little different on the 2000 model. Hopefully someone out there will have an idea of why this is happening, since the dealer's technicians had no idea.
I just worked on me friends 00 jeep grand cherokee limited with 121000 mil same problems changed cam and crank position sensor and. nothing changed. i saw an comment some where that the pcm wa the problem so i bought rebuilt pcm from autozone and stalling stopped. hope this helps.
