Hi on the OM642 engine there is a electrical component on the PCV breather assembly- arrowed on photo.

What is this part and what is it’s function?

Thanks in anticipation

I think it’s some form of air sensor . Probably to detect when the pcv valve at the other end releases pressure from the engine ?

Yes I was thinking like a temperature sensor as there are no holes or optics inside bore.
