- Had some problems with my 2001 Jeep Grand Cherokee Laredo 4.7L V8 stalling intermittently, and difficulty starting. Used a LELink OBD reader to pull codes, and found P0320 (with P0725 and P1281 pending). Research indicated crankshaft sensor and/or camshaft sensor could be a problem, so removed starter, O2 sensor, battery tray, and replaced those. Also swapped out Idle Air Control since I remember that helping in the past. All codes cleared after the repair, road tested well. Note the parts I ordered were: (1) Mopar 56028666AB Crankshaft Position Sensor, (2) Mopar 56041584AF Camshaft Position Sensor (both looked quite different than what I found inside), (3) Delphi CV10153 Idle Air Control Valve. Disclaimer: I am not a mechanic, just trying to DIY a problem.

UPDATE: I replaced the Intake Air Temperature (IAT) sensor and the Throttle Position Sensor (TPS) which were both easily accessible, and it runs even more smoothly. Wanted to replace the Manifold Absolute Pressure (MAP) sensor but I can't easily access one of the screws, so may try that some time. Bottom line: If you've got an old Jeep, replace all the sensors after you've had it about 15 years and it's bound to improve the engine performance.
Did you buy after market sensor or factory ones
@@franciscomelgoza8091 Always buy real oem sensors if you want to avoid change them again
Thank you for the helpful video. This was the only info for cam and crank sensor replacement for my 2000 WJ 4.7 that was spot on with locations and access. One MUST drop the starter to access the crank sensor which is directly above it and a bear to wiggle out. The cam sensor is easy once the battery tray is out. Again if working with a 4.7 V8 Grand Cherokee Limited this is your ticket for cam and crank sensors. Thank you.
To get trouble codes with 99 - 04 Jeep Grande Cherokee you just need to turn the ignition key to the on position 3 times in quick succession and trouble codes if any will apear where your mileage is.
This Jeep has been sitting up for 6 months I was about to order the computer and then I found this video$25 fix thank you very much, I replaced the crank sensor about 2 years ago so I figured I was good there
Thank you very very much just changed these two sensors and your video was a lifesaver. Great Work Sir i applaude you :D
Nice work-patient and thorough! Keepin' the old WJ going! Many thanks!
Top starter bolt - use a 2ft extension and a whobble bit. BTW, you have a light out on the dash.
I'm only 225K miles. So congrats to you. Mine is to haul around small trailers and my 3 dogs... :)
Absolutely love the combination of performance (at least 0-50) and bad weather traction. Its an animal in the rain. Not loving the gas milage - average 17 around town and 21 on extended highway trips.
That's exactly what my name year and model jeep does. It revs itself and sometimes stalls. When I first started working on it it wouldn't start, we replaced the starter and it would try but wouldn't continue idling then we replaced the crankshaft and camshaft sensor. That made it actually run but it would rev. Were in the process right now of replacing the IAC. It still needs to complete the relearn but I'm praying it fixes it cause this jeep has been down for about a year and a half now.
Also very informative video, most people dont even show the problem in action which is extremely helpful when diagnosing things on vehicles.
Any update? Same issue with mine. Replaced all that you have. It starts fine now, still revs randomly and wants to stall when I'm idling. If you can update id appreciate it, thanks.

Grate video and especially showing the symptoms was very helpful, thank you
Well put togeather and very informational video. Thanks Jim. Was able to follow right along with replacing both of my sensors. Really appreciate the work
bryson 12 thanks! I was hoping it would be useful. I was looking for something like this when I went to do my repair, but couldn’t find anything.
Great video my jeep just started having the same symptoms and had no idea where either sensor was
I Had the same problem with stalling my 01 4.7 Jeep Grand Cherokee and ended up being the camshaft sensor I also replaced fuel filter and cleaned the throttle body which I think helped as well. Before that I put a new crankshaft sensor but didn’t resolve the problem super annoying problem was finally SOLVED!!
Thank you so much for this video. It was a huge help!
My man, Thank you for the advice!
Great video, I'm not experiencing a P320 but a great video with spot-on editing!
How is your engine area so clean? I had trouble unplugging sensors for good 20 mins and you just barely use force and only couple fingers to get it off...you one lucky guy haha my mechanic work is determined by Murphys Law 🤣
Thanks bud. Nice camera work. Well see about the crankshaft sensor. Compared to tearing out dash a starter seems like a snap.
Fun fact about the wj if you cycle the key three times on the 3rd time it will show you what your codes are on the dash
This is sick af !!!! Thank you
Thanks again for the video. Knocked it out.
Thank you. My man going to get jealous when he finds out I know how to change the cam shaft sensor, he been looking all day for it.
Awesome video, thank you 😊
Excellent..Thanks for Sharing! I am now having the same error code..
Hi Jim. Very nice vid. Just one question, Have you ever changed the timing chain, tensors or whatever about the timing chain? I have the 2000 GC (european) with P0340 and P1391 codes but no idle or cruising issues, the engine light comes and goes randomly. I'm not sure that replacing the crankshaft and camshaft sensors is the way, any advise? many thanks.
Hi Jim !! thanks a lot for sharing your own experience, but can you tell me size screw support of Camshaft for necessary tool ??
Thank you ! I have to fix my own now,
What size washer did u use. I don't have any so ill have to buy some
Great Video. thanks.
Wait. I Thought the crank shaft p sensor was under the hood up top of motor right side right under the air box.... What sensor is that..
Gracias por el video los subtítulos ayudan mucho 👌🏼
Can't get the crankshaft sensor out! Update! I got it out! I used some 9" long nose locking pliers to clamp on to it and then used a medium sized crowbar wedged against it and a lot of tapping on it with a hammer. It was tedious and took a long time but that sucker finally came free.
Smart move. Mine wasn't seized per se but was in there pretty good... I sprayed it with WD-40 and spun it back and forth in the hole while pulling on it and it eventually came out.
How long did it take to undo the bottom left bolt next on the battery tray next to the steering arm?
I’m currently working on trying to remove it myself.
It’s a pain in the ass!! 🔧
Had the same issue on my wife's 2005 grand Cherokee...car kept stalling while driving , only I wish I knew I could do it myself!! Cost me 200 at the mechanics to fix
Good video
Super helpful. Thank you so much. I though the starter would have to come out all the way. (That higher RPM at start was my TPS.) Do you have any idea what that high-pitched whine is? Mine does it too.
Fuel Filter/Regulator. I my 2001 WJ 4.7 was cutting out at 3000-3500rpm. I had to try 2 different Filter/Regulator modules before I was successful. 232,000 on an original filter!
It says my ckp sensor is bad my truck starts right up? What does it do?
gracia amigo muy buen comentario voy ha solucionar el problema de mi camioneta
Great video. I'm confident to replace mine on my 2001 Limited
Thank You for this Great Video. I automatically thought it was the CPU, so I sent it off to be fixed. They said it was good. So, I am sure that this will fix my Jeep. Great.
Was changing mine today and snapped while prying it off. Make sure you use penetrating oil, I’m still trying to remove other remaining piece.
Hi Jim. Thanks for the video. I have a 2000 Jeep Grand Cherokee that randomly stalls out on me. After I let it sit for awhile it will restart. No codes are thrown. Interesting thing is that when it stalls the dash gauges stop working. I still have lights, radio and the engine will turn over. Did your dash gauges stop working as well when you stalled?
Hi Carl, I'm not sure, I think the gauges were still functioning when it stalled. RPMs would've been 0, but I don't think all the other gauges were flatlined. Sounds like it could be an electrical issue. Maybe disconnect and clean the battery terminals, check the fuses, or look for some dash-specific posts like this: www.cherokeeforum.com/f2/instrument-cluster-no-working-gauges-85883/
it is the black plug on the cpu mine does the same thing its a bad conection
I have that same issue, when it happens to me the dash gauges remain at current levels for about 2 seconds, then drop to zero. Wasn't anything like the tachometer behavior in this video
I am working on a 2000 Jeep Grand Cherokee with the same issue, it stalls, engine cranks and won't start. Gauges go down to zero, fuel gauge drops below empty even though there is over half a tank in it. Nothing is talking on the communication pci bus. Cycle the key off then back on then everything works and the jeep starts and runs fine until it stalls again.
Carl Stuart so here’s what I found out, the security system in the Jeep immobilizes the entire vehicle so sometimes the steering wheel locks and or your car stalls, it’s the camshaft sensor for sure cause I had to get mine switched cause whenever I brought it to more and more mechanics they couldn’t figure it out until I went deep searching on it.
I got a 2001 Jeep Grand Cherokee limited edition 4.7l, mine is doing same thing, starts up fine but after it warms up, it starts spitting an sputtering an shuts off, I just picked up a new camshaft an crank shaft sensor also, gonna replace them tomorrow, I've never really worked on vehicles alot, I mean I can do all the routine maintenance like oil an stuff, but I never did a job like this before, im gonna attempt it tomorrow, it looks pretty basic for the most part,
I have problema during travel to Tucson and then suddently my Jeep Grand Cherokee turn off... I was a little problemas to start it... And then I was able to arrive to my home... And then I could never turn it back on... I obtained two code P0320 & P0700 But I changed Crank Sensor Positions and Fuel Pump Sensor and the problemas was solved... After two days...
When you removed your o2 sensor do you have a check engine light on now
No it didn't cause a new check engine light problem.
I chickened out replacing mine. Was replacing starter and figured I’d do it, but couldn’t get the old one out!! Got it to spin, but not out. My mechanic buddy helping me said to leave it alone. Said the “socket” where it is is probably rusty and we were worried about breaking it or the new one not seating properly. What do you think? Should I have pried it out with a screwdriver and pliers? Thanks
Johnny's Cousin Steve I’m having the same problem any suggestions did you get it to work ?
If you know it needs replacing then yes pry it out. Try to get a screwdriver under the mounting tab and pry that out. Or clamp the sensor with vise grips and then use a pry bar on those as another commenter had said.
I have the same problem, but the check engine is off! Help!!!
thankyou my brother this venezuela
I'm getting p0320 withcheck engine light that turns on and off..but still reads on key code check.how do you know if it's cam or crank ?..im thinking it's crank because more of the start issues and stall speed gas etc..
You ever fix it?
Yo Jim I got the exact symptoms on my 02 limited but where’d u buy ur sensors from?
Just from Amazon: www.amazon.com/gp/product/B0055HYU7W www.amazon.com/gp/product/B006EFUGT0 www.amazon.com/gp/product/B000CGDCPC
are the crankshaft senser and camshaft senser interchangeable on 02 Dakota-4.7 ?
Sorry no idea
I already change the sensor but after a perfect ride, stills with the same problem again and i don't know what to do
I just change the crankshaft sensor cause that was the problem
I also replaced the IAT and TPS sensors, which were very easy, and it improved the rough idling significantly.
Working on the crankshaft position sensor rn and I'm really wishing the new one would pop in place just as easy. Any tips to get it in there? It's refusing to go into place
Clean the opening in the block and lubricate the rubber o-ring on the crank sensor with a little oil or grease... make sure you press it in straight... it's a tight fit, but it needs to be so that oil doesn't leak out.
so now after 1 year did any code come back ??by the way, you can get codes by switching ignition on and off , 3 times . It will display on the dash
Codes haven't come back, but haven't been driving it that much.
@@JimBeno so the fix was succesful? Sounds like I need to do the same..
I got stock trying to get the crankshaft out
What'd you do
what size washer did you use for the spacer? did it work?
I'm not sure what size it was, I just found a washer I had lying around. It worked well as far as I can tell. I would have been uncomfortable trying to tighten it up further and risk stripping the threads. There was a clear difference in the thickness of the tab. So the wash just served as filler material to close the gap.
Jim Beno thank you. im having an issue where it seems as if my sensors are pushed too far in. the tips are scratched up, so i heard to use a spacer so it doesnt rub. i just dont want to put too much of a gap and cause the same problems.
You know with this jeep you can turn the key on and off x3 and it will show you the codes OBDII
What size bolt u got for the cps
Either a 10 or a 13 mm. Think it was a 13 but I can't recall exactly. Just have a full set of metric sockets ready. A couple short extensions like 2" and 3" can come in handy for these kind of jobs also.
What's the big secret to keeping it going to 300,000 miles? I have an 01' GC 4.7 limited, about to begin the crankshaft sensor replacement. Thanks for the great vid by the way.
I had a new engine and transmission put in :) The engine ran dry when my oil pressure sensor died, and I had an oil leak that I wasn't aware of until it was too late.
i wonder if this will fix my jeep which randomly shuts off while driving.
Vi en un video con una situación como la que usted describe, me recomendaron cambiar el sensor de temperatura del refrigerante. Esto resuelve el problema que tienes
PCM fails on these too especially in warm climates. If you don’t have the p320 it could be the PCM
@@gatesj777 yea it didn't have a code but I got rid of that car n got myself something newer out the dealer
Great video overall, but you have to speak up, you replace some other sensor towards the end couldn't hear anything
Sorry first time documenting a job like this, will take your feedback for the next one :)
I have to tell you I think overall your vid is good, but after following it replacing the CPS and still getting the same results, then the part of the vid where you change another sensor? I can't hear A F'N THING
WHAT SENSOR AND WHY???
I"ve had three people listen can't make out what's happening at all
He mumbles a LOT
the cam sensor?
Idle Air Control Valve, sorry it wasn't meant to be a professional production, just figured I'd document the work in case it could help others.
I have a 2000 jeep Grand. Mine was running like crap. Like it was out of time. I had taken the starter out to get to the crank sensor and relised the bolt was broken off. The sensor was half way in. I guess the person that owned it before me snapped the crank sensor bolt off. I replaced the sensor. Im holing it in with rtv silicon cause its to tight to tap out for a new bolt. Runs good code p0320 is gone.
Easier to remove wheel
Speak up!
Good thing there were pics,couldnt hear a word you said
