BMW RANDOMLY STALLING? FIX IT NOW P0340 P0344 Intake and Exhaust Cam Sensor DIY

This DIY shows you how to replace both the intake and exhaust camshaft sensors on the m54 engine. This video applies to many models with the m54 and m52 engines (e53, e39, e46, e83, e60, and more!). A bad cam sensor can cause random stalling, check engine lights, misfires, hard starts, and more. Make sure you replace the sensor and the o-ring when doing this repair. #bmwrepair #bmw #mechanic

I just love the giggles when you start by saying, "you have to feel for the hole" Brilliant!!! I've always maintained the we'd make great gynaecologists, as much of our work is done by feel and mental imagery. I worked for a number of years in a Fiat dealership, the English translation,, from Italian, on every oil filter was: "lubricate ring and screw until tight" so many laughs were had. Never lose the schoolboy, or girl, sense of humour. I laughed out loud when you two got the giggles. Thank you for not editing it out 🙂

😂👍🏾

[@iljakozlovskis3321]

Before you "Fish the wire out" make sure you attach a lose wire to the connector with a duct tape and pull it out. That way you can re-attach the connector of the new sensor simply pull the other end of the lose wire to feed the new sensor connector with lead in the exact position of the old one. Work smart, not hard

[@pieterlastname1276]

Very good idea. Do u perhaps know the reason for this? I changed exhaust camshaft position sensor and the error codes never cleared.i have reset tool but the error reappears?

Ive fixed everything from fan clutch, thermostat, electric fan, cooling system, all sensors and brakes. Thanks man. One question: Does the 2001 325i have the electric vacuum control valve that connects to the check valve? Can't get a positive answer from anyone. Thanks again.

[@m00seknucklejohnson45]

Question my 04 530i has these same symptoms once the engine is up to temp it will die randomly while parked at idle, or like you said at a red light. Could the sensor need to be replaced without throwing the code for it? Or would it be more of the vacuum side of the motor?

[@mansoerdelong9598]

Thanks for video I'm having same problem with my e46 which also gave a code for cam position sensor

[@bmxican1023]

Is there anyway to decipher between intake and exhaust side sensors throwing the code? Thanks again for the video!

[@sbrave]

2000 328CI, 134k miles. I got a P0340 code after changing my pre-cam 02 sensors with new BOSCH sensors. I cleared the code and it didn't come back, but I've noticed the car in general can take a few cycles to start up, and the acceleration is not so great, especially when I floor it on the freeway. I feel like this car should be a lot zippier? Should I still replace 1 or both of the sensors? Thanks for the great videos!

[@KILLDEADPEOLE0928]

Thanks dude. I brought a 2000 323i sedan and loving it. Haven't had any issues stalling! Still getting the p0340 tho

[@pieterlastname1276]

HI, I have the P0339 on my M54. Would you please give me some guidance on that? Thanks so much

[@JomesZ]

My 2000 328i manual does this, on a cold start it idles high but as it warms up it almost dies and sometimes stalls. I`'ve had it couple times stall when I down shift to a lower gear. Do you think this will resolve my issue.

[@hammadrehman4257]

any idea if this code comes in conjunction with a very complicated P16A7 code? got an M54 and it just stalls out. Cats are definitely clogged but also have a tiny cylinder head crack. Car stalls out randomly (SMG). however It doesn’t happen when the MAF is unplugged. Maf was replaced with an OE part about 2 years ago.

[@MrJaz8088]

Hello I do have p0340 after head gasket job, I bought a brand new sensor, do you think o should retime the engine? The timing was perfect when I did it, with the 2 tools perfectly fitted, and also after turning one time the engine by hand

[@AndyNav1]

Hi and thanks for the video. Would you please tell me if these sensors are also called Crankshaft pulse generator? That's on M54. Thanks

[@afortunado81]

I have a 2012 BMW X5 I just bring it from Dallas TX to North Dakota , on the Hwy everything was very good, but went the cold temperatures start going to cero by Fargo nd the car stars with issues, low engine oil, low coolant and losing power as well , so I stopped in a gas station and get oil and coolant I was 2 hours away from home, luckily I made it safe, next day my wife took it to the grocery store and the car stars showing a lot a codes like battery needs to be Replaced and 4x4 needs service and misfire codes and camshaft sensors too. I’m just replace the battery already but I’m very confused with this camshafts and crankshaft sensors, can you please provide a part number for each sensors I need for this vehicle 🙏

[@josenoriega4324]

What would you do if you have all 4 sensors errors? I have a e65 2003 4.4lv8 with all four camshaft sensors reading high voltage?

[@MindHunger]

Thanks for this video, I just used it to replace my intake camshaft sensor. BTW as long as you are there, you may as well replace the intake VANOS solenoid as well. It's a wear item and it has to be removed anyway,

[@bazosmarek7981]

what are symptoms of vanos solenoid not working correctly?

[@krzysztofp7846]

THX BRO , the first one was intake or exhaust one?

[@friguy4444]

Always love your helpful great content. Thank you! I have had and I believe many people have a problem with mt S54 on my M3 stalling out often when I put the car into reverse as well once the car is hot and been running for a while the car just stalls out. Ive tried to figure this out as have many others. I can tell the change comes as soon as I put the car into reverse don't even have to use the clutch. The car starts stalling when i put it into reverse and it's idling. I had a BMW indie shop look at the car and try to figure out whats wrong. They checked the idle control valve but that wasn't the problem they did a software update and no good. My car is a swapped out 2002 330CI to a 2006 M3. Maybe that is part of the problem. As well when the car is hot and I push in the cltch and let the revs fall to idle it will just stall out even if the car is moving (Not in gear mind you). On and on it goes. LOL.

[@jdamore44]

I had a long crank- barely start condition. I've had intermittant CEL's for intake cam sensor, but no CEL this time. Could it still be the ICPS?

[@vsboss155]

check this, i had a crank but hard start. Changed oil filter & regulator/engine temp sensor/crankshaft sensor/fuel pump respectively, doesnt fix my issue. Switched the camshaft sensors between the intake and exhause, turns out i have a bad intake camshaft sensor. So now the bad one is in the exhaust side and the car starts fine.

[@MrJulio33gmail]

the e46 M52 has an additional vacuum line attached to the Fuel Pressure Regulator. Has any one done a catch can on an m52? If so, how did you tie in the Fuel Pressure Regulator vacuum line

I know on m54 you can cancel it out (or maybe reroute to top off gas thank, just an idea...), it’s only there if the pressure regulator fails and drips fuel.

Are these sensors also responsible for like when an M54 stallls for like a second and then continues to run? like when your idling at traffic light and you hear and feel it stall, lsee the rpm gauge drop, like it shuts off and then it picks up again?

Works on 90s, 2000s BMWs for over 5 years. Still uses sidecutters to get the intake airduckt clips out. xD No offense, just reminds me of myself xD. Them darn clippullers cost almost 5 bucks, money better spent on gas. xD Love your vids Keep it up.

[@oldduck887]

Did both sensors on my 2004 Z4, M54 3.0 engine. Similar but different. The intake sensor was the easiest. The exhaust sensor was very difficult to get to, too cramped of an area. Once I got it out I struggled to get the bolt started in the new part, I decided to take the electric fan out. Should have done that to begin with, one plug, one screw and one expanding rivet and the fan comes out. Anyone doing the exhaust sensor on a Z4, save yourself some frustration and remove the fan first.

[@S7midnight]

Hey 👋 I had a problem with stalling in m52, but it was the crank sensor problem. The symptoms for cam sensor is that you have to crank it a bit longer when starting and noisy injectors. Also could you explain why you don't recommend aftermarket sensors?

They can break more easily I guess oem fits the best and last longer

You didn't show the tail of the intake, alot of times I order the camshaft intake sensor and they have the wrong 1 listed at the auto parts store, it's usually the tail that's the tell tale, it's happened to me atleat 3 times on different m52tu engines, and the last time i didnt realize, and was fighting for the tail to push into the harness, when I realized what was going on I shaved down the guide rails and it snapped in perfect, took the car for a test drive and it drove perfect, but idled horrible... did some research, apparently the part is for the M54 or N52 cant remember... had to do it over again from an online store making sure the guides matched my old part in the pics, which for some reason they dont always show the tail....
