    Crank Sensor Dying Every Year.

    The Crank Sensor likely has died again, which could explain my horrible idle and car jumping around wanting to lean out or stall (usual symptoms) but lodged no codes, its exactly nearing its warranty period! Now I am not 100% sure because its night time here but I tested it and its supposed to read some 550ohm of resistance, but well this reads nil & once read 700ohm then died.

    I am buying from a local kiwi bmw parts specialist who's been a great place to deal so far, But these sensors are leaving a bad taste in my mouth, this is the second time in 2 years. This is become a regular maintenance of sorts, works good for half a year then starts to degrade, This was a oem vdo sensor, last one was a aftermarket one.

    Just for reference, a Good Crank Sensor should be around 550ohm with about 10% fault + or - 50 ohm either way.
    While, a Good Cam Shaft Sensor should be around 15ohm...

    Correction: The crankshaft position sensor needs to be replaced with the same type of sensor that is currently being used on the M52TU engine. Along with replacing the sensor an adapter harness must also be installed in order to supply the sensor with a 12V operating voltage instead of the 5 volts currently being supplied by the DME.

    NOTE: SOME VEHICLES LISTED IN DCS MAY ALREADY HAVE THE NEW STYLE SENSOR INSTALLED, FOR THESE VEHICLES A CHECK/VERIFICATION WILL ONLY BE NEEDED.

    Procedure: The following steps must be followed when replacing the original M52 crankshaft sensor withthe new M52TU sensor.
    1. Remove the crankshaft positionsensor which is located below the starter motor.
    Remove the Sensor (1)
    If the sensor currently installed in the vehicle has a connector directly on the sensor which can be disconnected, then the new sensor is already installed. No further action is required and the DCS contact can be closed.

    Note: Illustration shows location of component with air filter housing and air mass meter removed. It is not necessary to remove these components to perform this repair.

    2. The electrical connection of the crankshaft sensor to the engine harness is located below the intake manifold.
    To access this connector, the cap of the oil filter housing ( should be removed and the oil filter and housing should then be covered to prevent dirt from getting onto the
    oil filter.
    3. Disconnect the crankshaft position sensor (1) from the engine harness.
    Note: This illustration shows theplug connectors with the intake manifold removed. It is not necessary to remove the intake manifold in order to gain access to these connectors and complete this repair.
    4. 4. Remove the fuel rail cover and unplug the VANOS solenoid valve plug connector (2).
    5. 5. Install the new crankshaft position sensor (1) P/N 12141709616 and O-ring P/N 12 14 1 748 398.
    6. Install adapter harness P/N 12 51 4 592 703.
    a. Connect (1) to the new crankshaft position sensor.
    b. Connect (2) to the engine harness connector which was previously connected to the old crankshaft sensor located below the intake manifold.
    c. Connect (3) to the VANOS solenoid valve located on the VANOS unit.
    d. Connect (4) to the engine wiring harness connector which previously connected directly to the VANOS solenoid valve.
    7. After the adapter harness has been installed secure the harness lead going to the VANOS solenoid valve (1) to the VANOS oil line with 2 cable ties (3).
    Note: The harness lead going to the VANOS solenoid valve should not be under tension. The harness lead should be able to move.

    I have heard from people in the trade, that both on cam and crank sensors, but especially crank sensors, to buy BMW only. If you are, I don't know what to say, I've got over 300K miles now on M5x engines and have replaced only one cam sensor, and that was just recently. I may have been lucky, but you shouldn't be replacing them annually. As little as you enjoy replacing them, a shop likes it even less, if it comes back under warantee, they've got to eat the labor, even if they get the part for free, plus a less than happy customer who says why can't you fix it right the first time.

    I dont think that Sensor recall (using M52TU sensors harness) applies to european/jap cars as they were not fully obd 2. ? my sensor is in the front of the car.

    Have taken the crank sensor out of the car, to test the ohm reading, now this reads around 790ohm indoors!

    And just to test out I kept the known bad one from last year which is reading some 750ohm.. Heating it really hot with a heater for 5 mins got it down to 577ohm. So definitely out of spec and I guess it gets worse as I think the car warms up.

    This was a VDO, who may or may not have been the oem supplier at the time car was made, but today I asked the supplier that i wanted Genuine BMW made in Germany as the replacement.

    You measure 540 Ohm on your E36? From E32 I am sure, that is always 540 +/- 10% ohm. The old Bentley had a mistake once and mentioned for the M60 1200 ohm, this was later revised to 540 +/- 10%. https://wiki.bentleypublishers.com/d...specifications.
    Your CPS should be accdg to your VIN up to built year 09/1998 12141703277 and your car is a 10/1995 EURO spec 328i with M52 engine.
    newer cars have higher ohm, I checked on a German forum and someone mentioned 1280 Ohm "according to bmw original repair manual for a CPS on a E36 323i".
    Here in one offer is also mentioned 1300 Ohm http://www.daparto.de/Kurbelwellen-I...-178-95?page=3
    Bentley repair manual says -and they do not make any difference between early and late E36: 1280 +/- 10% ohm, airgap 1.0 +/- 0.3mm.

    Maybe someone can reconfirm that the CPS should read for the M52 engine 1280 +/- 10% ohm.

    Thanks for the info

    well i seem to be reading a lot on this and it suggests it should be around 550ohm for the s52/m52 motors.

    maybe some of us should do a measurement for the m50/m52/s52 motors that have the sensor in the front of the motor, just unplug it and test the resistance...

    - - - Updated - - -

    found this too just now..

    http://www.bimmerforums.com/forum/sh...osition-Sensor

    There are 2 specs for CPS (coil resistance):

    1. 540 ohms +- 10% for all models.
    2. 1280 ohms +-10% for model with breakerless ignition distribution.


    Anybody know which model excalty #2 refer to?? what is "breakerless ignition distribution" ? fuseless?

    According to Bentley manual, it say #1 is specs for M20/M30, and #2 for M50/M60 engines.

    Anyway, mine CPS reading is M50B25tu:395 ohms. And also I managed to measure few engines:

    M20B20: 679 ohms
    M50B20:405 ohms
    M52B20: 617 ohms
    M52B28:600 ohms
    I think within 500 - 600 is 10% fault tolerance, after that (read some pelican parts comments where the bad sensors/cars with problems had 700 or more ohm... i think as they degrade, easily heat effected, their resistance rises or lowers and cause mis reads..

    - - - Updated - - -

    another says

    Sounds like a crank sensor issue. Check the resistance with a digital multimeter. I think it should be - for the rear mounted one approx 540 Ohms. The front mounted one I think should be 1280 Ohms.
    - - - Updated - - -

    and here this guy sent fly a message

    https://www.youtube.com/watch?v=CMJFrHqCo7U
    Checking resistance on the sensor to see if it is faulty.

    The Bentley manual says it should read 1280ohms but in reality the sensor should be reading around 560 ohms +/- 10%

    pulse sender coil resistance at 20 degree C.
    with breakerless ignition distribution: M42, M43, M50, M60, S50, S38: 1280 +/-10%
    M models: 960 +/- 10% ohm
    distance from inductive pulse sender/ gear 1.0 +/- 0.3mm
    shop manual says this https://www.bmwtechinfo.com/repair/m...et1/311277.jpg
    But the shop manual is wrong with the M60 engine, apparently Bentley originally took these data from the shop manual and later revised it.

    Well, I remember reading as you say the 1280 +/- 10% was wrongly printed in the Bentley.

    Everything I read up on suggests it to be around the 500 range,

    Also what else is that my Known Failed Crank Sensor also reads 750ohm, now this sensor is said to have failed by the ecu in INPA, It caused the car a year ago to just stall once warmed up or misfire. changing it fixed the issue for almost a year till now.

    Now here's the shop manual, from my understanding

    Basically ALL Models from E31, E32,E34,E36,E38,E39 the Crank Sensor is indeed 540 Ohm +/- 10%.

    Except M Models (As M3/M5 S motors etc) only are 1280 Ohm +/- 10%



    - - - Updated - - -

    I found some info, So it has 2 BMW part numbers and a bunch of others too.

    Found some more info from the new revised Bently

    (Corrections made by them in red as states it should be indeed 540 ohm.. so my one is off..
    https://wiki.bentleypublishers.com/d...specifications


    how it worked all this time is something I wonder, perhaps just waiting to fully break down one day, or the stress put by the sc and added heat it cant cope as already its off the mark by a lot.

    Magnets are directly affected by heat, its law of electromagnetic. Just like thermodynamics. Heat effects air as heat (also a electromagnetic property) affects the properties of radiation expenditure.(ohms). That all in lames terms Of coarse and probably oversimplified.

    I Don have what brand I got from advanced, but I have the,box in the car at the garage. After three bad new ones you learn to keep everything for returns on a $100 part. The one I got that i remember about it, was actually mostly black plastic with just a nub of metal sticking out at the bottom. I was like "what is this cheap shit". Its been the best one so far. Will post the brand later tho. Be ready to spend the $100 tho. .

    Its within ten percent of 540. That a heated sensor. Or a operating temp situation anyway. There not heated internally obv.

    - - - Updated - - -

    But also to answer the question of how it worked while being off. The EcU is able to adjust its sensitivity with a particular magnetic sensor sometimes so that even tho a sensor closed resistance it maintance it pulse during use. So even tho your sensor was almost twice its resistance, it still could make an audible pulse that the me could interpret as a usable defined signal. That only lasts for so long tho. For instance I explained how my last cs would phase out when warmed, it lost more than the ten percent, which then,didn't stall, but left with intermediate result of random misfire. Work, work, not work scenario.

    That Bentley mentions: BMW E34 crankshaft position sensor - resistance specifications
    Applies to: BMW 5 Series 1989 - 1995 - 6 cylinder and 8 cylinder models (platform: E34)

    The change came same like on the E32 Bentley for the M60 engine, that was in the old Bentley 1280 ohm. (I assume) And when they refer to 6-cylinder, that could refer to the M30 engine, but also to M50? BMW shop manual mentions 1280 Ohm.

    Still not 100% clear to me.

    When you get the new CPS, please measure it.

    Here it says on bmw-e36 dot com: The crankshaft position sensor (CKP sensor BMW E36 M50)
    Testing CKP sensor:
    To check CKP sensor you need to remove the chip connector and measure the resistance between pin 1 and pin 2, which should be 1280 Ohms +-10% (see figure).
    In practice (in one case) floating CKP sensor failure led to the following problems:
    • Difficulty starting the engine (takes about 10 attempts).
    • Unstable idling, the engine was regularly stalling when going into idle mode.
    • Unstable operation at low and medium engine speeds, while in those moments when the reading sensor reads fine, but mostly it happened at high rpm, the engine runs in normal mode, the maximum speed and acceleration dynamics remained almost normal
    • Strange rpm readings when engine braking, for example when driving downhill - rpm arrow "jump" from 2500 rpm up to 2000 and back, thus changing the speed felt, but not as significant, it is most likely that the jerks due to a complete disconnection of fuel supply in moments of failure of the sensor, and tachometer readings - a consequence of false sensor readings.

    Replacement CKP sensor
    On the M50 motor CKP sensor is located at the front of the engine and detects the passage of teeth of the crankshaft pulley (see photo). For easy access to the sensor, it is necessary to remove the impeller or the right inlet of the cooler (after draining the coolant). Before installing the new sensor, it is desirable to strip the site for the correct positioning of the sensor is the gap between the sensor and the teeth of the pulley should be 1 +-0.3 mm.

    On the M50 engine fit some models CKP sensor by Bosch which cost several times less. The only drawback is the slightly shorter length of wire, which, however does not prevent its use.

    Position sensor engine crankshaft (CKP sensor) – induction type, is a coil with a magnetic core, the winding resistance is 880-900 Ohms. For normal operation of the control system it is necessary that the clearance between the sensor and the teeth of the disk was 0.5 – 1.0 mm. the sensor Cable must be firmly secured to prevent damage to the rotating parts of the engine and generator. At malfunction CKP sensor operation of the engine impossible http://bmw-e36.com/repair/210-the-cr...ensor-m50.html

    I have just bought the Genuine BMW Part as in Dealer Stuff OE (original equipment), the last part was OEM made by VDO. The place I buy them from were always a pleasure to deal with, Sensor is worth some $270NZD Alone, But they have knocked down the price for me as in the difference between the last VDO sensor and this one, So I only paid half that. Anyway the part should be here in the next day or two, just for sake of doing it, I will measure it and post back, will also be running the car in NA form and do some logs just to test things out how it performs without the blower and new Crank Sensor.

    Also they had this to say

    .....BMW actually buy these sensors from VDO , they wont have any difference in the quality what so ever , they will just be marked differently . the reason is, its actually illegal in Germany for a company to have a monopoly so a supplier ( such as Bosch & VDO etc) can also on sell the same parts to other suppliers but in this case, they are not allowed to on sell them with the BMW logo on them & that is the only difference.
    I worked for BMW them selves for 10 years & every now & then , even a Genuine part was short lived for no apparent reason, sometimes even straight out of the box there was an internal fault.
    Like I say, it can happen to even the best of brands....

    I have just decided to go with the Genuine BMW for my own sanity, and that it comes with 2 year warranty!

    When you got it, also let us know the BMW part number you are testing. Maybe also from the old Siemens VDO the part number you were using.

    Nobody would recertify these machines after somebody screwed with them without any visibility into what they did.

    Sure, that you tester is working properly? Try another one and measure again.
    And then contact your seller, he should know, as he mentioned that he worked for 10 years for BMW. Or he can test another one in their stock.

    I know its probably a simple solution for everyone else. But bear in mind the vehicle in question is using Siemens bits (I assume this one lacks the Bosch DME as well?), so there may well be differences in the way the sensors measure. Just the same as our O2 sensor has a harness connector under the car near the exhaust versus in the engine bay for Bosch-equipped vehicles.

    Just for the sake to deepen this mystery heres a full test of the sensors. Pictures attached below.
    Seller also said I should test the multimeter.

    I have tested my Multimeter with a 100OHM Resistor in the first picture

    As you can tell, its working properly


    Next

    1. Faulty Topran or Aftermarket Sensor 2014 - 2015 that was Declared Faulty by INPA Reads 775OHM

    2. VDO OEM Sensor 2015 - 2016 (worked well till now when car started having the same issues) reads 814OHM

    3. NEW Genuine BMW Sensor Bought Now, Out of the Box, Not Connected to Car Just Tested Reads 809OHM

    Quote Originally Posted by Seller

    What is the OHM’s you are getting as a reading & are you testing the right terminals? ( have you confirmed with another OHM meter & got the same reading )


    What reading are you getting from the other sensors , it would seem odd & amazing bad luck to have a car that requires its 4th crank sensor in less than 12 months ( The original, the OEM replacement, The Genuine replacement which you suspect is faulty & now the next one would make 4)

    I have never in my life had so many issues with the one car with one part ( crank sensor ), we sell these all the time & I have been selling these for 16 years now & never ever come across this before ever.

    Here's the pictures I took, for the seller/shop as proof. I wont disclose their business name as this may be just a batch of bad stuff I am being sent without them knowing. I have asked him to test a few in his stock if he can and if he has a multi meter. I have also asked a few other people.

    Correct, there is too much misinformation floating in the internet, and in addition that car in NZ is a EURO version, originally exported to Japan and then sold as used car from Japan to NZ. 10/95 328i Coupe with M52 engine, RHD, based on the VIN the CPS should be Pulse generator, crankshaft up to 09/1998 12141703277 , that is the one with the wire attached and plug in front of the engine.
    Oxygen sensor SIEMENS/L=990MM 2 up to 09/1995 11781427884

    CPS Cross numbers according to this list http://infopart.org/hella-6pu009110001-part
    BMW 12141703277
    BMW 1703277
    DELPHI DIESEL SS10893
    HELLA 009110001
    METZGER 0902004
    VDO 5WK9541
    VDO 5WK96041
    VDO S103557001D

    VDO S103557002B
    VDO S103557002Z
    VEMO V20720402

    well documented for the seller now by MisterM52, let's see what their reply is.
