The best explanation of setting the timing on this jeep engine I've seen. You can also put the two dots towards each other (not the compression stroke) and then use the toothpick through the side of the Oil Pump drive unit housing and through the alignment hole in the reluctor ring. Note this in NOT on the compression stroke which is confusing to most folks. The way you show is what you do if you want to set this all up ON the compression stroke. Very good explanation.
Thanks for posting up this video. Im on a 1600 mile trip in my 03' Jeep WJ w/4.0L and it just randomly cut off. Flipped the key 3 times n it sent code: P0340 being Crankshaft Position Sensor Circuit malfunction. So i just went ahead bought the Crankshaft position sensor & Camshaft position sensor, kill 2 birds with 1 stone.. Lol FYI for anyone that doesnt know DONT cheap out n buy any sensors that aint Mopar.. These motors dont like anything that isnt Mopar electrical wise
Thanks for your post Doc! I just R/R'ed an engine in a 2000 Jeep Cherokee and couldn't figure out why it wasn't running but forgot to set the timing until I looked at your post!!!!
interesting, i was taught that the two small holes, one in the housing and one in the rotor line up and put a piece of wire through the set it in making sure the cap connector faces straight backwards i have had mine installed for 1000 miles and runs great...but comparing it to yours one of us is 180 degrees out....does that matter?
Good video, but this is backwards from my 2001 XJ. The sensor would be facing front. And the dots are supposed to be facing each other. What am I missing?
I’m doing a long block 4.0 on a 99 Cherokee. Everywhere I look online there’s confusion. Your video shows you starting the engine so, do you think I should line my marks up like yours? Mine has a cam sensor too.
okay so how do you get the cam synchronizer to be "timed" dose the pulse senor just have be aligned with the leading edge? like how do you know what one is the leading edge? sorry this has been giving me problems for the past month :(
FYI - These instructions are 180 degrees off for a 2003 TJ 4.0. The camshaft sensor has to be installed with the tone ring on the other side for it to work.
He set the timing at 180 out so that he could use the leading edge that is also 180 out ,that's how it worked for him . Not sure why he didn't put the engine at tdc and use the alinemen holes?
when did we stop putting dot to dot? 99 to 2001 4.0 are alike and the book calls for dot to dot, you would be 180 out let me know how it runs after your done.
I thought on the timing chain the 2 dots next to each other was TDC on the compression stroke. When the dots are away from each other its top dead center not on compression stroke. It'll run might not tell a difference tho. This is what I was told. Any thoughts on this???
So what do you have to say about the 180 subject there Golden Guy. I thought your presentation was top notch and didn't fuck around but went straight for the nads. Furthermore I feel it worthy of explaining the differences noted here. Make is all feel a little more confident in what's goin on here and make you look bloody good at the same time. Thanks mate.
Wish you could have aligned up the timing cover and harmonic balancer TDC marks for folks doing the job with the engine in the vehicle, I think the dots on the timing gears go together and they are not at 12:00 which points straight UP. Does this part number not have an alignment pinhole through the outer housing to align the camshaft sensor drive timing? Thanks for the close-up pics. I thought 1998 to 2004 were the same?
I don't know if you figured yours out, but you can also put the two dots towards each other (not the compression stroke) and then use the toothpick through the side of the Oil Pump drive unit housing and through the alignment hole in the reluctor ring. Note this in NOT on the compression stroke which is confusing to most folks. The way he shows it here is what you do if you want to set this all up ON the compression stroke. In both cases the notch on the harmonic balancer will be at the pointer indicating TDC. It just one way of setting this all up is on the compression stroke (as he shows it) and the other way is on the exhaust stroke TDC (dots are together, use toothpick in alignment hole on Oil Pump drive shaft/Cam position sensor base). Hope this helps someone out...
great video, thanks, I have 04 jeep wrangler, I just did a rebuild down replacing lifters, rods, camshaft, cam sensor, plug, coil bar, gaskets, timing chain. followed another video about timing marks, mine were installed facing each other. I didn't see if #1 cylinder was at full up. car now runs, I have a misfire in cylinder 5 sometimes. going to change the plug again. Cars runs smooth other than the misfire. Here is the weird part, the Cam Sensor, now sits a 90 degree angle from your video. If not at 90 degrees, car wont start and if adjusted out of the 90, runs rough and stalls. thoughts? thanks?
I have a 01 GCJ Laredo 4.0. May I get advice on how I replace the camshaft sensor and the long piece that goes under it? Just a bit confused by the videos I have seen.
Just did this on a 02 grand Cherokee your instructions are 180 out the ring has to be in the leading edge on the other side also on oem can sensor there is a hole you can align up and stick a tooth pick in to make sure your lined up correct.
hi Michael im doing a 01 as well and can not seem to get timing right on it. with your comment on this are you saying the two dots on the timing gears have to be facing on another or just like the on in this video?
The vehicle came in with a check engine for miss firing codes and would buck and loose power under hard acceleration on the highway but would run fine at idle and around town it would run good when you cleared the codes the cam sensor had a lot of play and would move up and down . Replaced the sensor and synced the timing and vehicle ran great after that.
+Charlie Charlie when I did the cam sensor I did not pull the timing cover I just put it on TDC and set the harmonic balancer on 0 if you buy an oem sensor it comes with an alignment tool also there is a hole in the sensor housing and on the cam fazer those two holes will line up with each other it would have it installed correctly also once you are finished you need a scan tool to set the cam and crank sync at zero or your vehicle will run rough.
The question 80% of us are searching online. Do we need to do all this extra stuff or can we just plug and play the new sensor. I’m still looking for this answer to my annoying code that popes up for it once and a while.
i have a 2004 wrangler rubicon 4.0 am trying to install the sensor and syncronizer but it was running rough. where are the timing marks on the timing chain cover i found it on the harmonic balancer but cant find it on the cover?
What's the chances of a faulty oil pump causing the cam positioning sensor to stop working? I've noticed my oil pressure dropping over the last month or so. It works some times and then drops some times. What's been strange is the Cam Sensor has been ticking. So I assume it's actually caused the cam sensor to miss time?
I just rebuilt engine 4.0 jeep2001 can't get it to start it spits a d sputters like its out of time but checked timming numerous times what have I missed?
hey i need yalls help i own a 2002 jeep grand cherokee 4.0L and it just started to run real rough and shuts off with now the oil gauge on H this morning it stayed between H and normal. but still runs rough. i took it to auto zone they hooked up thier code reader i didnt get the codes but he said its either your timing belt or your oil pressure switch. i changed out pressure switch and did nothing. could it be the timing belt? or could it be the crankshaft sensor PLEASE HELP
The video is good but wrong. all data and other sources show the reluctor facing the other way. in other words it is 180 degrees out of time. just fixed it on a 2001 xj. it solved all issues.
If you install the cam and crank dots facing right at each other and don't ever turn the crank, that would be true. He has the crank turned to where the cam is 180 off. If you install it his way, it will work. However, if you pull an engine and turn the crank when you're tightening flex plate bolts that goes out the window and you can only strictly feel for TDC. He should have made two videos, one for aligning the crank and cam the way he did and using the above method, then another one for feeling for TDC and then aligning. When all else fails just use the toothpick method to lock the pulse ring in place and install the sensor that way.
@@waynesanders1406 You seem to know what you are talking about. I have a 01 GCJ 4.0. I bought them camshaft position sensor and the long shaft thing that goes under it. How do I replace that?
Great video but x3 on the tone ring it was wrong for a 2004 wrangler rubicon 4.0. It has to be 180 out on these instruction otherwise save my butt. Thanks everyone who contributed
My 2004 jeep lorado NO!! The timing chain wont last the life time of the car i just changed mine yesterday and it had over a inch of play in it. Its not suspost to move that much i changed the cam shaft sensor and the camshaft synchronizer if u do not have both pices lined up perfect it will run rough like mine i have to take it bach off and set it again if u just change the synsor it has to be set right to u cant just put it on it wont start or run rough so if ur jeep is runing rough its prob the camshaft synsor

Can’t you just take the old sensor off and put the new one in? Do you have to take out the drive assembly?

Do I need to be at TDC if I didn't remove the distributor or just simply change the sensor
No

i wonder if that isn't the problem with mine to, what years yours
the oil pressure gauge doing this is nornal along with speedo..
Nice video, but wrong for 2005-2006 4.0. Those have a much different camshaft sensor and slightly different location.
please help i have play in the top rotor of the oilpump drive...first distributorless 4.0 i just wanna know if theres suppoded to be any play there
I just rebuilt engine 4.0 jeep2001 can't get it to start it spits a d sputters like its out of time but checked timming numerous times what have I missed?
Did you ever find out what was causing this I have the same problem
You shoukd corret title: 2005 and 2006 don't have the same..
i jave a 2001 and have same setup
2000 4.0 reluctor faces opposite at tdc. Video is incorrect.

+Aaron Worthington The Jeep doesn't have a timing belt, it got a timing chain and they last the life of car.
+michaelheiland123654
timing chains do not last the life of the car. ever..
Gmoank if you change the oil on time it will
I got that repaired a year ago claim down
i had my oil changed on time everytime and it went out so yea this part does go out over time. and doesnt last a life time. lol

He just marked the wrong side with the red paint, that’s all.
The timing is right.
That engine kinda sounds annoying with that scraping sound
There is no 4.6 jeep engine.
