Thank you Martin... My Son and I have been fighting this issue for a while. We had other crazy codes that just confused us. Finally put in shop for diagnostic's they narrowed it down and only wanted 600 to do the job. Funny but not funny our poor boy shop wanted much less. Thanks again and have a blessed day. 8 -2-2023 Barry and Jeffrey "Colorado"

[@randybonner9870]

Helpful tip . If you're experiencing the bolts falling out of the socket when trying to install the new sensor , put a piece of paper towel or a piece of tape over the opening of the 11mm socket. This will snug up the bolt and keep it from falling out of the socket when trying to alien it . Works great for any bolt that's in a position to jst fall out or get lost in the engine compartment. Example, some bolts that hold down the distributor cap don't always stay with the cap when you're trying to unbolt the cap. The bolt will just fall into the Netherworld of forever lost bolts . Use anything thin paperlike that will snug up the bolt to stay in the socket.

[@dnb3810]

As I'm preparing to do this job, you're advice sounds fantastically helpful. Glad I saw this comment, thank you.

the most simplest and easiest to watch video on CPS in the internet ! very inforamtive. keep going, cheers mate !

[@martinbuilt]

Wow, thanks, glad it helped.

[@rain4rusty]

I spent a week trying to figure this out. I live in mountain jungle of Chiapas Mexico and I am very lucky this failure did not happen in the middle of nowhere. It is the same symptom as a fuel pump failure and relay failure. Thanks you very, very much!!!

[@rain4rusty]

PS. I also spent hours looking for the right video, thanks again!

[@martinbuilt]

I'm glad you found this video and it helped you out. Yeah the crank Shaft position sensor code many times does not even show up. I carry a code reader with me all the time including many other other parts that could fail on the trail just in case.

[@rain4rusty]

@@martinbuilt Thanks again, by the way a cracked intake manifold hose made it even more difficult to detect the problem. I may have cracked it during my hose checking. I purposely use a 1995 4.0 engine system so I don't need a reader I do it by using the ignition key to get the computer codes.

[@martinbuilt]

@@rain4rusty Good to hear that you got it running again.👍

[@jonraper9]

Thanks for the video, really helped me verify a problem "fingers crossed" and the extra long extension is key. I also took of my front drive shaft and it gave me some extra room!

[@CherokeeXJ40]

Just replaced mine as you did along with your exact method. Was a SOB for me but got it lol. I went 4wheeling up to the top of Mt Siegel at 9500' elevation near Minden, NV and literally when I reached the top and stopped, the Jeep died. I couldn't believe it. Thankfully 10 minutes later it fired again and I went home and replaced it as I have two CPS's on hand. Thank you sir for your video and have subscribed.

Cleanest xj undercarriage I’ve ever seen.

[@martinbuilt]

Thank you

[@rsvp6]

I have done this on a 2000 XJ. Took a little longer than this video shows (mine isn't as clean), but process was the same a lot of extensions and wobble socket. I had a intermittent failure as described but did not get the code right away. dropped the bolts a couple of times but this is exactly how it works. I now also cay a crank and cam position sensor both in ba of essentials. Both of these things will kill your motor dead and no work around. Heer is my best pro tip. DO NOT buy the cheap knock off no matter how tempting. Pony up the $100 bucks and only do this job once !!!!!! Another tool for those that don't have lift kit. You will need a jack and good jack stands to fit under there. Thanks for all of the great content, really enjoy this chanel.

[@scorpion2005765]

I've been chasing the same problem for weeks on my 99. Replacing sensors after sensors that mechanics recommend. My XJ has never thrown a code. I'm definitely going to try this sensor next.

[@foxmulder7616]

What was your problem with your xj?

[@rikkwakeupwesternworld9874]

Great video and well documented just might add to be VERY careful that neither of the bolts when loose happen to fall into the hole where the CPS fits, its easily done, some models have a plastic cover that prevents this. Sometimes its missing, mine was and before I realized I had one of the mounting bolts fall through the hole into the bell housing. Had to take the bottom access cover off and use a long magnet to retrieve it. Mechanics tip is to use petroleum jelly so it sticks in the socket especially when putting new one in. However once all connected started immediately, used similar long extension and a ratchet.

[@frankbotello9475]

This literally happened to me today lol. Had to take the bottoms cover off as well and use a magnet stick to get it out. But good tip using the petroleum jelly👍🏼

[@playlude99]

Oh man, I wish I had seen this comment first. I just dropped mine in there and spent like 20 minutes looking around for it. I had no idea that hole was there.

[@conan670431]

Hi there , can you cut a little hatch on the side of the bell and have an access port there as on the WJ's to reach the sensor easily if on the road or just to make it easier to do the repairs? The sensor was totally diff on my 2002 WJ 4l straight with a single bolt holding it .

[@Timk0810]

Just successfully replaced the CPS on my '99 Cherokee. I had about 1.5-2' of extension from the ratchet up. I used a piece of tape to hold onto the screws as I was threading them back in. Place the tape over the socket sticky side facing out and push the bolt into the socket. This should hold it well enough for you to get the thread started. I had to disconnect the front drive shaft to get my arm up in there, but I was very close to being able to do this job without removing it so probably will vary person to person. I have an OBD II bluetooth scanner tool which was giving me the code P1391. I actually had to turn the engine off with the ignition on to clear the code. I tried clearing the code a few times with the engine running and it wouldn't clear. Great video! Thank you!

[@diekatzefliegt]

Martin as always thank you so much for your wealth of info. For the first time since owning it my wj left me stranded for a couple mins on my way home tonight... tach dropped and felt like misfiring, pulled over and restarted after a min and drove fine. p0320 code, guess its safe to say ill be doing this sensor tomorrow

i had a local shop screw up mine. so next time i did mine. i located the location next to gas pedal right next to the carpeted hump next to the shifter, cut a small hole with a drill bit ,go under and located where bit came out. then using a large hole saw in a drill cut a larger hole,then using sheet metal snips made the hole bigger. now with a light you can see everything and even touch it with your hands. use sheet metal and screws to patch hole pull carpet back into place .mine is a 1988 cherokee this made life sooooo much better .jeep should have done this. also use a cardboard business card to space the sensor so it doesnt scape

they ripped off the cover and threw it away bolts where not tight. like i said when i wrote my reply. i located where it was located next to the drive shaft hump next to the gas pedal .drilled a small hole after pulling carpet back then took a metal hole saw and cut a hole and then enlarged the hole and now i could see and put my hands on the sensor , put a sheet metal patch to cover hole then put carpet back in place. it was a 1988 jep cherokee that i bought new@@foxmulder7616

I am having a very similar problem with my 97 tj and from this video I found the wire cover leading to the cps had been resting against the block and had melted to the wire. It is only short circuiting when it's very hot outside. This probably solved my problem.

If it was there before you started it is most likely falling down inside the bellhousing remove the inspection cover at the bottom of the bell housing to retrieve it.

[@boiboi8417]

[@AlphaBobFloridaOverlord]

Just did my 2002 TJ 4.0 Manual Transmission. The connection for my crankshaft position sensor is on the passenger side of the vehicle down near the oil pressure sensor. After I completed the job I wondered if I had jacked up the frame slightly and put jackstands under the frame rails (NOT the axles), if that would give me a little more clearance on top of the transmission. Additionally, there is a rubber boot that is supposed to surround the sensor. It was missing on my 275,000 mile vehicle, but I’m going to order and install it within the next week or so. I think contamination from the open hole probably shortened the life of the sensor I replaced. Also, I used an NGK/NTK sensor which is the only other brand, other than Mopar, that I’ll use. Time will tell!

Grateful for the insight. Though I did get the garage to change the CPS. First problem I have had with my 4L petrol 2002, as I only drive it sparingly here in London (but carry bricks, cement and stuff!) It's only done 67000. It stopped 5x the last 28 miles, started up again each time after a few attempts. Hope it will see me through now on my (83+) last run without having to get anything new. Battered, but best car I have had!

[@martinbuilt]

Those 4.0 engines will run for ever.😎

[@johnowanda]

@@martinbuilt Unfortunately, the replacement of the CPS did not change the situation. The car occasionally, and not long after starting, just dies out (though it has run in between incidents for 30 miles or so without doing it at all) , it has happened at least 6+ times in the last 100 miles. I can also feel "voids" when I drive it. Often it just requires two turns of the ignition to get going again but on two occasion it required multiple attempts, I thought I was draining the battery! then the engine revs roar ahead only to drop and die down quickly unless you catch them mid stream and sustain the middle level, and then it settles down within a couple of minutes. It will then run for miles and miles without any problem. I thought it might be a fuel contamination and thought that the petrol filter was under the bonnet but the garage tells me in this 2002 model, its in the tank, so I will take it in again and get them to drain it and see if this is the problem There were instances here in North London of contaminated petrol and "Morrison" one of the supermarkets had to compensate a number of drivers but "Tesco" where I got mine just before the problem started denied they had any such problem. The garage excluded it might be the coil, but then what do I know?

[@steveburton2410]

Excellent how-to! Exactly what I need to know, no extraneous BS. How well does that 'cabin air intake' work for ya...never seen that before!

Im doing a engine swap with my 01 wj 4.0. Should probably replace this sensor when i do so. Would tell me what sensors i should replace when doing an engine swap, i think the cps sensor for the 2ed generation grand cherokee is a bit more challenging than this due to a smaller hood and less room between the bell housing and firewall.

Appreciate your video- I'm a 67 yr old widow that has found myself learning and even doing some repairs myself. I'm pretty sure this is my problem. I have 2000 jeep Cherokee sport. What about the 02 sensor or fuse? Should I check that as well? If so where is it? AND About 3 days after mine went out and parked it started a leak on passenger side just about under where the seat is. Would this have anything to do with that sensor going out? Do you know what it might be? It baffles me that the leak would start and the car hadn't been driven. I've never had a leak on this vehicle. I did have the oil pan replaced a few months ago!

[@martinbuilt]

If your Jeep has the symptoms I described in the video then I would suggest the crank shaft position sensor. the 02 sensor would never cause the vehicle to stall or not to start. If you have a oil leak in the center of the vehicle then I would suspect a rear main oil seal or a transmission or transfer case.

What would happen if the sensor completely went out? Cause my xj went dead on the way home and the 30amp fuse keeps going out went i flip the key. I think my auto shut down relay turns off my pump if it’s not getting a good reading from the crank sensor. Please let me know what you think and thank you for the video

[@martinbuilt]

I don't think the crank shaft position sensor could cause a 30 am fuse to blow.

[@richtyler1353]

I have one question. How did you get your bolts to stay in your socket. Mine kept wanting to fallout every time I bumped it trying to get the extension up in there. Do you have a magnetic socket

[@martinbuilt]

It was probably the dirt that was packed on the bolt that made it easier for me you may want to try adding some grease to the socket and the bolt will stay in there.

Hey. I have question? I have the P320 code. Im changing out tomorrow. Looks like a 15 min job. Did you by any chance have headlight flicker also. Hopefully I don't have another issue. With the wiring. I have 98 cherokee sport.

[@geostanley409]

What head casting do you run on your xj?

[@jethro9341]

A failing CPS is also a commonly overlooked cause for a random misfire, just the code (P0300) and an actual felt misfire/rough idle.

[@martinbuilt]

yeah the CPS can cause random misfire.

[@jethro9341]

I had a random misfire on 2000 xj a few years ago. The cps was the last part I tired and it worked. Fast forward to a few days ago, now my 2001 xj has misfire on #3. My dumbass jumps straight to the cps. No dice. So I do plugs and coil rail. Still no worky. I see on interwebs to swap injectors. Sure enough, misfire followed the injector to #1. I pull it and look again and found a giant crack right down the side of the guilty injector. Note to self: start with the easy stuff first. The worst part is I already knew that!

[@airbar2684]

I see you don't have a dust cover around your sensor. Is it required?

I noticed your black dust cover your bell housing is missing, how has your Jeep been running after the replacement CPS, did you need to re set the PCM? Thanks for your video.

yeah, that is missing, it's been running great.

[@RHYMESMOKE1]

Great video.. 👍👍👍 So I have most likely a dumb question. Does the bolted side have an actual plug? Or does it just sit in the hole? I'm going to attempt to replace this, also the tps, and pickup coil/camshaft position sensor. She cranks but no start, and I got back OBD 1 codes in my 95 Grand Cherokee for camshaft position, throttle position, and crankshaft position. This is the most difficult replacement out of the 3 due to location, and putting the bolts back in without extensions. Just wondering if can it be swapped out, but not bolted back? Or would it just be a risk of having an issue. Again...might be a dumb question, but I haven't gotten the new one yet, but does it not have an actual plug on the bolted end and that's why it's bolted? Does it just rest there? Thanks

[@nicholasridiculous3488]

Thanks for the video man, I believe this is my problem also.

[@martinbuilt]

It most likely is good luck with that.

[@23rdMS_Inf]

Great video. I just have a question. How did you get it so clean under there? Mine had over 300,000 miles when I bought it and there's so much gunk and build up (presumably carbon) that I can hardly see anything, and whenever I do any work I have to wear a suit, mask, glasses, and head covering because it literally gets everywhere.

[@martinbuilt]

use some purple power or super clean and then pressure wash it will do wonders.

[@darrenvogel8096]

I was also wondering if the ground cable from the battery to the frame is neccesary

If it came with one I would not delete it. Good grounds are important.

@@darrenvogel8096 don't forget the 2 grounds on the block passenger side below distributor or coilpack. Which ever 1 you have. 1 by battery passenger side on top the wheel well and around the same area drivers side as well. 1 on the firewall straight back behind the head (valve cover). Its late so might be forgetting 1 so make to sure to check everywhere because that can fuk up the electrical system or cause certain shit to act up.

@@martinbuilt In the mornings my 88 Comanche with the Peugeot would always be hard to shift. I forced it into 2nd and it stalled and never restarted. I changed the fuel filter and pump and that wasn't it. It will start, putt-putt for 30 sec or so and then die. My best guess is the CPS, would you agree?
