How to test the intake camshaft position sensor on a 2001 - 2005 BMW 3 Series (E46) with an M54 engine. The vehicle had a P0340 stored. For more information on Bentley Publishers line of BMW technical manuals, visit www.bentleypublishers.com/
Thank you to our friends at Autologic for the use of the Autologic BMW scan tool. www.autologic.us - Auta a dopravní prostředky
Excellent tech vid chaps! I like that you went back with the oscilloscope to verify your expected results.
Love the level of detail, great stuff.
@dyzenment That was an error in the title. The description of video and content in video is correct. The title has been corrected to reflect this. Thanks for catching the error.
Great info,, help me narrow my problem down on my e39 528i. I used c110 diagnosis tool to graph cam signal and got same results, no cam signal, now it time to replace cam sensor. Thanks for info, happy diagnosing.
Very helpful. Thanks for the video.
Can you guys do a crankshaft sensor repair.
معلومات قيمة شكرا
واريد مساعدتكم .عندي BMW 120D .2005 كلش يمشي ماعدي للمبة الديزور طافية ومتثورش .جربنا سكنار ومحبش يقراها .وسكرا
DO YOU HAVE ANY VIDEO ABOUT MAP (MANIFOLD ABSOLUTE PRESSURE)?
2006 BMW 330i, my cam sensor pop up. it goes off and back on. Does the type os gas have any effect on the sensor. mechanics been checkn and chasin still nothing. vanos, timing, and cam sensor checked to be good. so I dump in some gas treatment havent seen check engine light since then..
Helo my BMW e46 1.9 l has 10 v instead of 5v on conector to cam position sensors, .an ideea someone?
have 2005 bmw 325i, exact same symptoms hard starts and stalling on occasion. used bmw scan tool and did live test with the intake position sensor and car stalled when test initiated. bad cam sensor?nreplacing anyway but just learningto use scan tool
What if I am getting 0V in the sensor reference signal? is the 5V supply an ecu supplied voltage ?. I changed the sensor with a new one, but keep getting the same fault code returned 2a63. Seems to me the sensor is never getting the 5V signal it needs to work with. Doe anyone have a pin-out of the ecu as this is clearly not a cam sensor fault.
I'm having troubles removing the VANOS solenoid to get to the intake camshaft position sensor. It seems pretty stuck. I sprayed it down with some Bolt Off, but had no luck. I'm using an adjustable wrench. Any suggestions?
I have a 2003 bmw e46 sedan..when i drive it for extended time, especially on hot days-(summer time) shut the car off for at lease 5mins then try2 start it back up again. it wont start! the temp needle jumps into the red. as if the car was overheating, it locks-up, nd wont start un-till the engine cool's off again, the needle never goes into the red zone while im driving thought, only when i stop and then shut the car off ive been struggling with this problem for 2yrs now with this car
I have an e87 1 series BMW with a half yellow engine warnig, codes 2a67 and 2a6B I know it it something related to the valvetronic. Do you happen to know if it is the valvetronic sensor or if it is the valvetronic motor, or something else? I hope it is not the sensor that I have to replace ecause it costs a lot. Thanks
What do I do if I'm not receiving the square wave from dcm?
Mine is e46 BMW 2004 make,2000cc.Was slow in picking speed and had a "eml" on the screen. I drove it for some time and eventually it just stoped and wouldn't start again.Im now being told it had to do with vvti.We replaced the motor but it didn't help.what can I do ?
Is there a reason why the "before" video shows no movement in BOTH intake and exhaust cam angles. Where as your "after" video shows both cam angles moving. If one is faulty, does it default and stop the other one from moving too?
btw, I mean I am getting 0V steady (always 0 volts).
Where can I get a scanner like this?
would both the exhaust & intake sensor failing cause it to stall & not restart? One or both?
Yes
Hey...i have a big problem with my 2004, x5, 3.0 engine. The problem started a few months ago and is driving me crazy. I start the car now...run it for...10 minutes or 5 hours, i stop the engine. Try to start it after 30 minutes around, the car turns and turns until i push the gas pedal. It starts and it feels like it's not enough fuel or too much fuel. Do you think it might be from this intake camshaft? I changed : Camshaft exhaust, crankshaft, fuel filter, sparks, clean idle control, clean throtle body, clean auxiliar air pump...new air filter...i have no ideea what's wrong with it.. :( Please, any ideea?

Hello,
Hard to know what could be wrong without doing some diagnostics. Check carefully all connectors. Look at the front vibration damper. Make sure the rubber is not loose on the hub. Next you should connect a scan tool and see what the live data looks like when the engine is running. A BMW service professional can use a scan tool to look at the live data and determine what numbers are out of range. I'd recommend a good independent based on the age of your X5. Could be a mass air flow sensor, a temp sensor, a cam sensor, or other things. Sorry I can't be of more help, but arm chair diagnosis from here. Connect a scan tool and go from there. Assuming the check engine light is on, so there should be some fault codes stored. good luck and let me know what you find. -Charlie B
BentleyPublishers Thank you for your answer. I have a BMW scanner and a live data program. Nothing, everything looks good, that's strange. No engine light on... Nothing! As soon as the car starts drives like new. I just used FCP EURO for some parts now. Waiting on the camshaft sensor, the one that's up because the other one it's changed already and got the temperature sensor too, the one that sits in the block engine. Hope one of them is the problem. To be continued...
did you solved?
Were you able to solve this problem because I am having this problem also
Is it P0340 or P0369. In the video you say P0340 but in the title it is P0369?
Skip to 2:46 for the real action ...
That sounds more like a problem related to the thermostat and cooling system. I have a feeling you will get Fault code 10 and 123, 10 being: Coolant Temperature sensor, and 123 being: Characteristic Map Cooling - faulty thermostat, or no / incorrect activation by the ECU. Go to a licensed BMW workshop, or a BMW workshop and have your car diagnosed.
im sitting and laughin how you test signal for squerwave,man you disconected plug from sensor and tested to harnes ecu side not connected to sensor. so hows its posible to see a signal if sensor is not connected
Exactly,LOL
Hustler LT i could have sworn he said " plug sensor back in" and then plugged it back in.
intresting topic but presentation need improvement
