1982 924 Turbo Crank Position Sensor

[HabitualSpeeder]

I picked up an '82 924 turbo, a few months ago. [Yay!]

It needs a crank position sensor (part number 93160602100). [not so yay.]

I've tried searching for this part with little luck. However, I might've found a parts car, which is good (if the car has a compatible part).

Anyone know if an '81 924 turbo has the same part? From what I understand, the '79 & '80 models don't.

Any help would be appreciated.

Indeed, the '81 part is the same. The part itself though, is no longer available elsewhere. Here's a blurb on said topic, if you can muddle thru the high-tech talk!

All S2 (1981-onward) cars use the same crank reference sensor.

Same part is also found on early 944s, used only for diagnostic purposes at the dealer. . .mention this to broaden your net if you are looking for a salvage part.

I could be wrong, but I don't think that is correct. The 931 part number does not appear in the 1985 PET for the 944. I recall there being some speculation that the diagnostic sender would work, but I also recall getting a used one and verifying that it is not the same as the 931 "impulse sender". I think I still have it lying around the shop.

Looks that way! The 944 part actually has a 911 part number, but I could have sworn I read somewhere it was the same piece as the 931.

Oops!

Yeah, I already found out the hard way this part is a little difficult to find.

I have quite a few resources to find parts and it just doesn't exist.

So, I figured I'd stop looking amongst the folks that know what the part is & search amongst the folks that don't know what they have...hence, the parts car I found.

Thanks for the info, folks!

I was under the impression that these are unobtanium new. 81-82 should be the same part.

Alternately, you can swap to a MSD system here.

The diagnostic sender on wifey's 87 944 looked suspiciously like the crank sensor that came out of her 82 931. Might be worth looking up the specs.

[ideola]

From what I recall, they are not the same, at least not dimensionally. I seem to remember that the 944 unit is longer and has a larger diameter; it also has a flat rectangular piece sticking out of the end, which the 931 unit does not have. Specs are nowhere to be found, but it would be interesting to put them both on a scope.

For anyone that's curious...

The crank position sensor from the parts car I found worked fine.

I need this same part (crank sensor #93160602100)

[Drewcoop13]

Did you find the part ever?? I need one

[ideola]

This part is not available anywhere. Your only hope is to find a 1981-82 parts car and hope that the sensor is intact and functional.

Any luck with comparing signals on scope of the 944 diag sensor? There's a tonne of those laying around. In have one in a box somewhere. I'll pull it out and measure it and get some scope waveforms.

[ideola]

Won't matter. The 944 unit is a single winding unit, the 931 unit is dual winding.

[DannoXYZ]

Here's picture of 944 diag sensor. I'll put this back in the car tomorrow and scope it to see what kind of waveforms it generates. Impedance is also a lot lower than the 944 units.

Wow, why not just go standalone? Seems like less of a hassle. Run whatever hardware you want... especially when a lot of parts are NLA.

(sorry, can't help but cheerlead)

that's a lot more cost and effort than replacing just a single sensor.

Do you have a waveform from this sensor? Looks like the 2nd coil may super-impose another signal on top of the 1st one?
