Running great after the diagnosis? Reminds me of when my maternal aunt was diagnosed with Tuberculosis in the 70's and had to go for an Xray....she said to the radiologist, after being invited to put her clothing back on, "D'you know, I feel much better already, thankk you so much!"

Reminds me of my sister's garage door alarm contact sensor. After living in the home for 20 years, all of a sudden the alarm started going off while she was away. Using a couple of pieces of plastic, I raised the magnet off the concrete floor to get it closer to the sensor on the door. Weakened magnet problem solved, no parts required, except an old old plastic ice cream container.

Hummm. Car runs fine after three weeks after installing all the old stuff back. Almost sounds pin or wiring issue. I've had fixed problems by disconnecting and reconnecting before.

sometimes rust gathers in the hole the crankshaft position sensor is in and it causes intermittent contact with the reluctor ring, make sure the hole is clean. it can cause a bigger gap than it needs.

My launch gets into the old and new how's, check the temp sensor, they were an issue on the older bm's causing a crank no start

Might be that after the engine's been started the heat alters the crank sensor causing it to work.

I suspect the old Autel will work. My Launch connects.to my 97 Z3 however for the ABS it gave me the wrong fault codes. Luckily I tried creating a few more faults of my own only to find it was totally messed up. My Launch and old red brick snap on agreed.

I want a pico bad. My verus is ok but i cant get clarity and detail like that. I had a similar issue with a output speed sensor.

Actually fixed one of these many moons ago Ivan. The young kid doing the engine swap had put the crank pulley on without referencing the keyway. Suspected the crank position sensor all along until I did a timing check. Nice job Ivan!

Thank you! I would love to see your reliable Autel DS708 trying to communicate with this oldy

It makes me wonder if possibly the ECM just isn't receiving some kind of input to tell it a start attempt is being made. OBD I vehicles are somewhat quirky in that respect. Part of the beauty of them is that they almost always have some way of retrieving DTCs without a scan tool (jumping connector pins, cycling the ignition switch multiple times, turning a mode selector screw). I would figure that as long as the crank sensor can provide half a volt positive and negative, the ECM should be able to read it properly (based on my experience). The only other variable I can think of is that the actual cranking speed is not fast enough. It could also use an oil pressure switch input for confirmation.

Some had the stomp Test koeo stomp gas Pedal 5 times light on dash blinks the codes No scan tool needed 👍

Would it have helped to break out the can signal and test network for 120 ohms to see if a module was pulling down communications?

I love how all the other comments are wise cracks & small talk.

It is possible to find a middle ground and buy the OEM sensor, without having the BMW logo stamped on it. This sensor is most likely a Hella unit which is available in the aftermarket. I replaced the one in my 1992 BMW with a Hella unit from RockAuto. Made in Italy so not cheap junk, and the price was fair. On these cars it has to be Bosch, Hella, MAHLE, Stabilus etc. The cheaper stuff doesn't work.

I think BMW was the last to fully join the ODBII bandwagon, somewhere along the line I think they added the bus to the 20 pin. but my BMW-fu is minimal :))

Water in the computer?? Has the water issue been addressed?? Of course this could be the reason for the new ECM not starting perhaps after rain.. Also a thought on the strange communication waveforms could be due to your scope settings, you were running a long timebase which could give you a odd waveform. Thanks for the great case study!!!

Tape an iron washer to the end of the CKP to help minimize the air gap?

Ground strap issue while cranking ?

First I have to comment on the one minute to put the crank position sensor in on my Kia optima I believe that's considered a six or eight hour job... Yes I have done it in the parking lot of my apartment complex and it was not fun perhaps it was even the most difficult job I've ever done...

Sometimes you have to just shake your head, laugh and move on to the next one...

Is there a fuel pump control module that the fuel pump relay connects to, as in some Ford products. If so, check for corrosion and high resistance on that end of the circuit. In many cars, turning on the ignition is what activates the fuel pump, so that there is enough fuel pressure to start the car, which you were not getting consistently. You indicated that the 5 volt circuit was slightly too low - generally a sign of resistance due to corrosion in a ground or a corroded or loose connector, and you were manually connecting the fuel pump wire to that relay connector, always a bad sign. OBD-1 or -2 standards and protocols had not been finalized when that car was built, and were not required to be complied with on BMWs in 93/94; thus any trouble codes were all proprietary to BMW, which is why your equipment wasn't helping you. Looks like a bad circuit to the fuel pump and a gap at the crank sensor that is at the edge of being too wide.

Would you be able to re-magnetize the CKP by either running a large DC current through it, or by winding a wire around it and running a large current through that wire? Just like you do to re-magnetize your old screwdrivers? It could make this a no-parts-required fix :-)

Wondering how water got into the PCM's business and whether anything was done to stop the new PCM from getting baptized... Also wondering about rust jacking increasing the air gap 'tween the ckp and the spinning thingy. A ckp sensor can be checked for ohm-age, no? Might be instructive to compare the old OEM, new OEM, genuine aftermarket Chinesium for ohm-age and amplitude.

"JUNK!" Truer words have never been said, LOL!

Try a heat gun on it when its cold. Also moisture may have seeked into the crank sensor.

Crank damper is soft and when cold, belt tension causes too large a crank sensor gap. Repl crank damper.

Just move the VRS sensor closer to the wheel with teeth that will rise the amplitude and perhaps fix it.

We can hear some banging in the background, Did you hire a helper like Erik O.

Looking to pick up an 05 bmw 7 series no crank no start. Very very cheap. Why scan tool would you suggest going with ?

My mother had a 1989 eagle premier with a 3 L V6. After a few years it started giving exactly this problem. Crank position sensor was usually the cause. Replaced a couple factory units. However you also had to adjust the clearance on that sensor using a multimeter. It had to be just right. You had to do this while the engine was cranking. Stupid design

Why does the amplitude of crank position sensor (blue line) goes high with the engine rpm? The sensors usually generate pulses by switching on and off. Changing amplitude means the switched signal voltage is changing?

For the 91-93 red bosch labeld ecu there are no universal readers that can communicate. Even inpa has no database for them, just abs and airbag. But that problem is 99,9999% a faulty cam sensor. It will start. But when it's acting up you gone have to crank it for minutes, then it somehow overides one of the sensors and fire up. All in all that ecu is simple as fuck and just works

a magnetic sensor always has more amplitude and frequency with speed, the hall effect sensors are the ones that use a high and low type of square wave.

The crank sensor amplitude is RPM dependent, perhaps the starter is cranking a bit too slow?

I was "Like 666", with 6 dislikes, kind of a weird coincidence. BMW went out of their way to make diagnosis difficult, that connector is just another tactic they use to make BMW seem special.

Last one I did had a broken crank sensor wire damaged by the owner when he didn't notice the broken cooling hose and instead swapped out the thermostat in response to an overheat issue. I found the sensor wire under the top thermostat bolt, and was not surprised, everything this guy touches turns into a no start/no run. He was so cheap that the car sat for 4 years before they finally brought it to me for the no start. He declined the cooling hose repair, and then complained about losing coolant. It seems the only thing worse than a BMW is a poor customer trying to look cool in BMW, but has no money.
