Are you a Professional Bmw Mechanic My whole family was wondering because your the only mechanic on UA-cam that explains a lot and every little part to make things easy when taking BMW’s apart Love your Channel
He is a beast and we all love 50s kid
You have no idea how much of a head ache you saved me from! I am adding one of these sensors to a M30 powered E30 right now and couldn't get this level of description anywhere else for the wiring. THANK YOU!
Very good explanation! Greetings from good old Germany. I am happy that you Americans love ouer German cars so much.
The best channel on the net for DIYs. Thank you for helping the BMW community. Keep up the great work
I know Im asking randomly but does anyone know of a tool to log back into an Instagram account??
I was dumb forgot my login password. I would love any tips you can give me.
@Zayd Kamari instablaster :)
@Jericho Kayson Thanks so much for your reply. I got to the site on google and I'm trying it out atm.
Seems to take quite some time so I will get back to you later with my results.
@Jericho Kayson It worked and I finally got access to my account again. I am so happy:D
Thanks so much, you saved my ass !
@Zayd Kamari no problem :)
That test of the sensor with the wrench is awesome! So obvious, yet my engineering mind didn't think of it. Kudos!
I had a po340 on my 330i and i've just replaced the sensor following this guide(my replacement sensor was also similar to yours,delphi brand). it was very helpful and glad to say my car is now running fine again with full power. I also cleaned the maf out with some electrical cleaner and noticed a gain in G/s on my OBD2
keep up them guides 50skid. might try a fuel filter/regulator next.
Owen did u get shaking while idling ??? I have a 330i too plz reply
@@vvtheonevv4007yeah please answer coz I’m having the same problem
If all of your videos are this detailed I am extremely happy. Shop wants to charge me 1k to replace both sensors intake and exhaust. After watching this, it feel like i could just do it myself. Thanks.
Today I replaced both my intake and exhaust camshaft sensors after watching you video.
Note: I had both P0365 (and sometimes P0369) and P0344
My car was suffering from poor performance in low to mid-range rpm, didn't feel like the car was moving until it reched 4k+ rpm, seemingly random stalls all the time, and often when shifting from R to D. It's been sluggish like this since I bought it a couple months ago.
Noe it feels like a new car! Power is back and I feel the car is more responsive. I was worried the VANOS was bad and I'd be needing to replace the seals, but it seems VANOS is working nicely still (but will prob. replace seals down the line)
Thanks for the video!
I successfully changed my valve cover gasket using your guidance; my next project will be these sensors. Thanks for the great content. It demystifies DIY.
You've helped me on several occasions keeping my newly aquired 2003 bmw 330xi on the road! Just replace Camshaft Position Sensor in about 30 min and she is purring again! Great stuff kid!
Great video as al a as man. I did this exact job a few months ago, it's refreshing to get a full explanation of how it really works.
If you would have approached it with the mindset of replacing all problem areas, you'd have been good to go.
I love your videos! You don't just show what to do, you explain why.
This is why I really enjoy his videos
Thanks guys, that is what I always aim to do. I don't like doing something unless I know the why behind it.
@@50sKid mine is 320i if the intake sensor is plugin its a long crank and has a check engine and if you unplug it and start it it will go like normal start but still has a chec engine and loss of power
@@50sKid can you help please. My fuel pump is working. All fuses and relay are working but the e46 will not start. If I apply full accelerator is will try to turn over. I have gotten it started this way and it will run fine once started. Can't find any air leaks as well
@@50sKid hello have an bmw e39 1998 m52 520i when on cold start the rpm goes up and down like it gon turn off if you dont hit the gas pedal and the accleration si not constant its good when the car is cold but when it is hot or driven more the accleration is sluggish not enough power but sometimes the power comes back and goes away again no engine light no nothing just not enough power it feels like the car is heavy like a army tank haha i dont know how to explain it better please help please
Had the P0344 code and managed to find an OEM sensor with the BMW logo scratched off on eBay for $60. Easy DIY job, thanks!
Did this today - a very straightforward job. Not as easy as the other one, but that one is almost comical... any M54 job that doesn't begin with "... remove the air box" is an easy one!
I renewed my VANOS solenoid o-ring and cleaned the electrical contacts, while I was in there 😉
I cured my stalling problem thanks to this.
Thank you, all great videos, I'm a new 323Cic owner so these videos are great to help me keep this classic (almost) on the road.!
Great video! Thanks for all the details and giving us some knowledge on what this part truly does. My 525i just stalled on me while I was driving today. Let it sit for a few hours and tried it again. Thank god it started right up. Brought it home and started my research. Code came up for camshaft intake sensor.
Thanks so much for this video, and really all of your E46 videos! I don't know where I'd be without them. Only issue I ran into is the wire on the sensor got hung up when I tried to pull it through, which took a while to get unhooked.
I am from germany and i had not found a german video for this problem at an e46. Thank you really much i will follow your channel :)
This guy is actually author of the system for BMW.
Good to learn from you always
My M3 E46 2001
Vibrates when idling, when accelerates pick up slow sometimes, when changing gears I feel clunk, aircon not working and can not working in automatic mode( just once the engine starts running, the fan just start running)
Lastly the vehicle when driving steering is shaking and the vehicle is not in good balance
So glad with all your video content. It's my nr.1 source for m54 repairs. Thanks again!
Excellent video, thank you very much. Unfortunately I did use the MEYLE replacement part and it failed after a short time (less than 100 km.). Maybe save time and expense by replacing with the original BMW part to save yourself time and expense. MEYLE factory said no recall on the sensor, no warranty, no refund although my big beef isn't the expense but the inconvenience and frustration of having to buy another sensor and do it all again.
Great video man, it really helped. I am a math jockey who just bought his first car and this is one of the issues it came with. I saw it was a cheap fix and bought it but had no idea how to do it xD. One watch and it is solved, thank you so much. I'll be keeping up with you and recommending you to my friends who are also buying their first cars. Thanks!
Great video and explanation. Glad you added the circuit part. I hope you can include this in your future electrical content.
Hi 50sKid, I actually own a 2001 330CI (Restoring)and have viewed a few of your helpful videos. Keep up the Great work. Cheers.
I love these videos so much and I use these all the time on my bmw
Your a legend, just done mine and after watching your video it made it so easy. Runs a treat now. Many thanks
Omg!!!! Thank you I’ve been looking for a damn vid that explains it cause I did my ccv then I did t realize my clip flew off and stalled my car while driving I forgot where it connected too thank you!!!
Bruh, loved the detailed explanation. Appeals to my OCD.
excellent video... all the jobs are made far easier by this instruction.. did this in about 20 minutes. Perfect. the one caveat is I would use a genuine part for this job because the non oem sensors are not reliable. around 100 bucks for the real genuine sensor.
Thanks for uploading and sharing this! I actually found it unnecessary to remove anything but the Vanos cylinder which I loosened with some pliars and then got to the sensor.
I do recommend to everyone to buy a BMW sensor though. It's three times the price of the aftermarket ones but I too had the experience that the aftermarket one I bought (SWAG) immediately threw an error code - something the original 20 year old and 250.000mls sensor didn't do. Bought and installed the BMW one and all is good.
Some people say the exhaust camshaft sensor determines startup behavior but in my case all issues I had with warm starts, engine dying, idle fluctuations all went away with the new intake side camshaft sensor.
Thanks again @50skid
Without any kind of testing with several sensors from different manufacturers you cannot really say a BMW sensor works any different than any other sensor ? It's also possible to purchase a new faulty sensor from any manufacturer.
Thank you!
I appreciate your online classes on the functions of the car.
Thank you for your work. My e46 threw a the P00344 code yesterday. Your video is great. -Michael.
Great information. Just purchased a 01 330ci coupe and can use all the help I can get.
You’re so great man , thanks for all the videos.
Thanks for your videos they have been very helpful especially with diagnostics and being very informative with your explanations all the time.
Really appreciate the Help, and thanks for the 'how to test/how it works' info!
awesome video as always, you are my go to guy for my BMW
hey! just found your channel, love the quality and the great way you show everything! keep up you're awesomeness! - Norway
I never thought I would ever see BMW mechanic using an adjustable wrench!
Why not? A wrench is a wrench, dude.
I love your channel and I admire your knowledge, but from experience none of those engines tolerate the aftermarket camshaft sensors. They just don’t last very long. It’s always better to spend a little more and buy the genuine position sensor from BMW. I just replaced mine and it cost me around 118€ here in Germany :)
Thank you for including the white board session.
Excellent video and explanation. I was afraid to do this before seeing it.
I see you ordered the off brand sensor. Has it given any issues again? I Just bought the BMW one from your affiliate link... and a bunch of other vacuum lines and random stuff... Thanks for the video - pretty sure you have helped the world. Stay awesome.
You just saved me $1000 on my 2001 E46 🍻🍻
The best channel ever!
Thanks for this! Didnt know it was this easy to replace!
I had to change my Intake Camshaft Position Sensor on my BMW E46 2001. I ignored all of the forum warnings and bought an aftermarket sensor and the new sensor didn't work that well. Car would still stall once in a while. I then bought an OEM sensor and never had an issue since (has been 4 years now). So make sure you purchase an OEM sensor.
Which aftermarket sensor did you buy?
It was Beck Arnley. They have great control arms and other suspension components.
Interesting. Always good to know what manufacturer is bad when it comes to each component.
THANK YOU, THANK YOU, THANK YOU, words cannot express.
Try the piston app works great and it's free gives a lot of info so far haven't had anything happen that it didn't diagnos with the proper code erases all fault codes also
i have a 2002 bmw 325i with a p0340 intake cam position sensor code. i went ahead and changed it and still the same. i changed all three senors, both cam and the one crank position sensor. STILL P0340!!!!!!!!. i have tested all sensors and connectors and getting all the proper voltage. STILL P0340!!!!!!!!
Great video Thanks. I replaced the A side sensor and it worked perfect until I drove the car a few times then boom - same problem and same code. I used the same brand sensor you did (Myley I think).
Same, what you did?
The whiteboard feature is cool. Not new, but cool and much more useful and applicable than... you know;)
So I replaced mine because my 02 325i was intermittently turning off while driving after a while. Rough idle and would shut off at idle and all the other symptoms for a camshaft sensor. So I replaced it with the thicker one like in the video. Mine came with the one you had too (thinner). And was still giving me the same code. So I'm gonna replace it with a replacement and hope it was the design or a faulty part. Will update when I find out......... code was p0340 only.
Wow perfect explanation with you my car is on point thanks
Check your battery! I had the same code.. changed sensor.. Still the same. It was the battery! Bloody thing.
Also check your oil if you have minor leak. Because if you've ignored it.. then only topped up so the light goes off and tricked the oil sensor.. sooner or later you'll go near empty and the pressure will play up.
Issue I had in my e46 company and solved..
Man I got to hang out with you, I would live in the engine compartment if we were neighbors...
got the p0340 code after replacing both sensors (and valve cover gasket) with a hella brand. also car now has intermittent hard starts and shuts off randomly at low rpm
Best video I watched so far
I have a BMW e46 318i, it has rough vibration on idling, my mechanic can't find the problem this is what we did so far:
Replaced MAF Sensor
Replaced Timing chain tensioner
Replaced all mounts including tranny
Replaced idler tensioner pulley
Can the Vibration be caused by this same sensor?
No a sensor wouldn't cause vibration
mat I ask if you have any suggestions?
thanks mate...
i have some wire check tomorrow .. i have p0340 code for some time and i replace 3 till now , 2 cheap and one FEBI (good one) ,
but problem and code is still the same. cold is all good but when its hot and i turn him off , after starting him staling and no power at all.
i order also exhaust position sensor to try that also .
thanks for video.
new sub on your canal...
cheers
Nico Despot I had p0340 p0335 and p1318. The problem was the wire to the intake and exhaust cam sensors was routed behind vanos solenoid instead of in front.
@@blainegabbertgabonemhofgoa6602 yes I think I have same problem.
I will check wiring tomorrow..
Thanks for reply.
Cheers 🍻
@@blainegabbertgabonemhofgoa6602 What are you implying? That the routing of the intake or exhaust cam sensors wiring behind the vanos solenoid was the reason that it's ok when cold and faulty when hot?
Enuf Ots idk about the cold hot thing I didn’t have that problem on my car. All i had on my car was the three codes I mentioned and no other problems or symptoms and it ran fine.
GREAT explanation, thanks! (Now a question..) is there any way to check cam timing on a dual vanos, without pulling it all apart and using the timing adjustment tool? I have a p0340 after the engine rebuild..which was set with NO TOOL, and then checked with a tool with no locking squares for cam, and no crankshaft pin. So. I'm afraid it's more than the sensor. Anyway to check cam timing? Thanks again...
For All, Never buy Meyle or else, always from HELLA, BMW buying this Sensors from HELLA and putting there BMW Logo and sell for high money, only HELLA Sensors the Rest are Bad, if you Lucky it work Bit of Time and you buy again new one
Greetings from Germany, like your Videos ❤
about the sensor, the new BMW OEM sensor has been modified and has the same dimensions as the mayle's sensor that you used.
Ah, I was kinda wondering! Thanks for contributing that!
Mine had a camshaft position sensor 1529. Only thing I can think is a wire having been somehow bumped when I did the PCV / CCV system (thanks for a great primer on the system.
Love your videos, but things like this is why I sold me e46, it seems like every two weeks it needed something. The car was cool, but I didn't have the time to keep fixing it.
Any issues with your gm5 module too creates havoc with the electrics of left. Dodge battery ruined mine, dunno why, changed camshaft sensor code still being thrown… got gm5 module repaired once my window wipers stopped (was the final straw after central locking), solved it… lol
Big thanks for the great video.I have manage to change by my self save a £100 labour lol.
Hi i recently changed my camshaft sensor and after changing got a code saying the sensor is too advanced, then right after started to get misfiring codes and fuel too rich followed by fuel mix too lean. Also to note the too advance code went away but the other codes remained along with misfiring fuel cut in cylinder 4,5,6 which caused the check engine light to come on for the first time since owning the car.. Also to note once reusing the old non-working camshaft sensor the check engine light went off and all the above codes went away with just the camshaft position sensor code present.
Thank you for your videos, they have helped me a lot with my e46, in this case, to measure the 12v, 5v and ground signal, did you leave the key turned on in the ignition?
You had cam fault codes indicating faulty cam sensor. So in the video you removed it and tested voltages and the cam sensor function on the multimeter and it was shown to be working fine ? What I dont get is why an OEM sensor is over $100 but a branded Meyle sensors is $40 but still considered good. It can't be good as the OEM sensor is an extra $60 so must contain more electronics and process signals faster giving more advanced and acurate timing signals to the ECU.
Thanks a lot, please keep up the good work!
I love this channel!
Can these run fine when cold, but once warmed up they make the car stall, run poorly, etc?
Hey 50's kid late to the Party but have wathched your videos since i got my 2000 e46 I just replaced the CCV breazther hose and and Intake Cam shaft Sensor. which was p1397 cleared it test drove it and now throwing P0340 A (which is intake) and now the car has no low end power or when i try to get on it. And the engine quits while just going at slow speeds. And I dont know what to do. and I am to far to drive to the BMW mechanics. Any help would be great.
I love your brain man ❤️
Yes, my E53 had this problem. This CAM sensor was the bad boy.
Changed the CPS, before it was idling way too high . Now the idle is slow to drop to almost normal but Im getting the 404 code. The car is running good other than that
Our car is a 2001 330ci cabby' with about 85K miles on it, never seen winter. This is it's third CPS, the OEM then a Dorman but this time i went back to OEM. Years ago it failed an E-test, the tech came outside with his reader and showed me why, told me to take it foe a long drive and bring it back the next day for a retest. Bingo , it worked the car passed the test. Today we took it for a good long drive, just got home it's idling perfect , no ECL's and running like a charm, sometimes the simple things are the answer.
Hello,
Are you sure it has to be 5 volts on signal wire? I am reading 11.8 volts on signal wire. Is there something wrong with my car? It also gives me a fault code 2781 and also it gives a error when trying to learn the valvetronic position. Is a N42 engine. What do you think?
Which one is the actual cam shaft position sensor that one or the other one in front?
I replaced my sensor on e46 316i from 2000. My car loses rpm it drops all the way to 500rpm and it turns of by it self. Also it happened while i was driving. When my mechanic conected it to diagnostics its saying camshaft sensor but we replaced it and i have still same problem. Also on my board i dont have any light problem no check engine nothing. Can you please help me what should i do? Thanks
I Have the P1338 on my 2005 325i, is it the same sensor problem or is it a different problem??
Hi, would the eml light be on when this goes bad? Mine is on and can’t rev up past 2000 rpm. And it stalls. But i have no codes
it it the same type of sensor that is used for intake and exhaust?
You must have been through everything in the engine bay. If I touch one thing out of place it snaps because it’s dry rotted. PCV valve tube broke the first time I did my vanos :(
So there's something I can't quite wrap my head around and that is, at around 13 mins into the video you test the sensor with a wrench, splicing into the 5v signal and you can clearly see the voltage drop, but it appears you're using the old sensor. Wouldn't that mean the old sensor was still functioning? How come replacing it fixed your problem?
I recently bought an e46, it has a M52TUB20 in it. The engine runs like it's brand new, there's no check engine lights or anything, however it's got no power to speak of whatsoever, you have to rev it really high to really get it going and even then it definitely does not feel like it's a 150hp car. It also has an extremely laggy throttle response. Like if you turn it on and just jab the gas pedal to the floor real quick and release it, it'll still be accelerating while your foot is already off the pedal and then dropping the revs almost a second after.
So i've tried running an obd on it and it came back with four codes, P0159 - bank 2 second o2 sensor slow response, P0160 - same sensor no response, P1622 - MAP cooling thermostat control circuit (which I'm absolutely clueless as what it could possibly be) and the P0340. So I've tried unhooking the sensor and turning the igniton to position 2 and It would appear like I'm not geting neither the 12v or the 5v input while the ground appears to be good. Does anyone have any clue what could be causing this or what my next step should be?
Cheers.
I think the sensor has 2 steps of failure, on mine it first started failing when starting the car already hot, but it can also fail so you can't start at all. Maybe his was only giving him problems while hot, that's why it seemed it was working on the multimeter.
I'm not an expert but I think that could be the explanation
@@petarjuric8455 The wiring to the sensor is very close to the heat of the engine and will deteriote over time causing errorneous signals to ECU. THe actual sensor is probably fine but a multimeter cannot really mimic the conditions within the engine bay to effectively test it. Heat also affects the strength of a magnetic field and weaken the magnet within the sensor also giving inaccurate signal levels. If your engine is extremely hot then the sensors can fail causing timing and starting issues.
Heyoo so I replaced both cam sensors and I'm still having problems
Thanks for all your vids, my bmw isling goes up and down and up and down them it settles and iddle correctly, could this be the sensor or the vanos
good video thank you bro, doing good jobs
Hi I got the phone app and the ELM 327 unit, but where do you plug in the ELM 327 unit into the car?
Will this put my car in limp mode? I have this code. 171, 102, 313 and 560
Just wondering how the Meyle cam position sensor withstood the rigors of time. The OEM item is ridiculously expensive.
i forgot to plug the intake CPS wire back into the harness after doing the CCV replacement (many thanks to your informative videos), I restarted the car and the idle was so smooth that I didn't realize anything was wrong. Took it for a test drive, and you are absolutely right, VERY LITTLE power in the low RPMs, like the camshafts arent moving. Found out it was unplugged later. My question, is the VANOS functioning if this sensor is unplugged? More specifically, If i had a VANOS rattle, would I hear it if this sensor was unplugged? Many thanks!
No it will be in limp mode
Very helpful, and thank you.
I replaced my camshaft position sensor as per your video and connected everything back together. Now I get the code P1519. Any idea what could that be? The car drives fine, does not stall, no loss of power. Initially I did the sensor because I was getting P0340 however the car was performing fine with just an occasional harder start, I would have to turn it a bit longer.
what can be the problem I checked my cam sensor wires no power and my fuse is right
Is there maybe a relay or something that does that
Same here
Subscribed :)
Thank you for sharing the videos
The part that you took off before the sensor . I cannot get mine off . My tool wanted to just start stripping the edges . What can I do to get it off . Also what is it
Hi 50'sKid! In your experience, what do you think the likelihood would be of both camshaft position sensors AND crank sensor failing all at once be? My 2000 328Ci stalled on the highway the other day for the first time ever, and then continued to stall randomly for the rest of the day after that. (Got it towed home no problem, so all is well)... My code reader gave me several faults, accompanied by codes P1397, P0340, and P0335. Can you shed any light on this? Thanks!! Drew
Does the e46 or 330i/ci have an eccentric shaft sensor on all models or does the camshaft position sensor function in the same capacity? I have been looking for the location of the eccentric shaft sensor on my engine and can’t seem to find it… I haven’t opened the valves yet, and really want avoid it unless I know for a fact that it has that part… the reason I ask is when I go online to search the part the camshaft position sensor keeps popping up, and when I find an e46 eccentric shaft sensor I can’t find one compatible with my 330ci…only the 330i…. I don’t want to go off buying a part that I don’t need and opening a part of the engine I don’t need to…
