I need to get a new cht sensor for my 74 2L. Are all the ones good for my car? All the ones I have found seem to have the same part number. Just curious if there are differences between engines sizes etc???

Thanks in advance.

Original sensor was for 70-73 1.7
VW 311 906 081A
Bosch 0 280 130 003

This sensor was superceded by :
VW 022 906 041A
Bosch 0 280 130 012

Rare sensor for 1973 2.0L :
Bosch 0 280 130 017

The Uro one will work, cheap enough although quality is questionable, the wire pulled out of my first one!

This is the number I have been finding. Just wanted to make sure it will work on my car.

How does one test a CHT before installation?
