I need a correct Cylinder Head Temp (CHT) Sensor for my '73 2.0. I need this part:
022 906 041 A (Porsche/VW part number) and/or 0 280 130 017 (Bosch part number).

My engine had an unlabeled sensor in there, and I have a couple of 012 sensors (which are correct for later 2.0's, but not '73s).

Please let me know what you have. Thanks!

P.S. I already have the ballast resistor to go with the sensor. So, just need the correct sensor.

Not cheap.

Ouch! You're not kidding.

Anyone have a good used one, at a more-reasonable price?

$25

Thanks for the link, but unfortunately for me, those are 012 CHT sensors. I need an 017 sensor. You can see the part numbers listed on Brad Anders' page: https://members.rennlist.com/pbanders/DJetParts.htm

Aase is selling 311 906 041 A, and I need 022 906 041 A. The part numbers are the same except for the first three digits.

The difference in resistance is only when cold.

017 = 1600 ohm

012 = 3200 ohm

But when hot both are ~ < 100 ohm

( these numbers are from memory, so could be off a little )

When you add the resistor you should be good.
especially after the engine is warmed up a bit.

So IMHO the 012 will work for you, but good luck with your search for the CORRECT one.

Btw. Part sold… someone wanted it.

I have 6 cylinder head Sencers and they are so small where do they put the number .some have no number the rest have a three digit number like 772 . is it the last 3 digit you are looking for ?
