Quick knock sensor OBD2 question (pic included)

[Leo_328i]

Alright guys.

Putting my M52 back together but I forgot to take note of which knock sensor goes where.



Which lead goes to the back of the block closer to the firewall and which one is near the front?

EDIT: Or does it not matter?

[328ijunkie]

It does matter. Ill see if i cant remember.

Thanks mate that'd be greatly appreciated

If anyone has a picture of their engine bay with the inlet manifold removed that may have the answer there too!

That's for an N52 not M52 FYI.


But you should be fine following it.

How is that for an N52? It says its for M52!

No u right, I clicked the link at the bottom and the 3rd option took me to N52 tq specs. Figured the TIS was about the N52 when it just details tq spec for various engines, even mini.

Those are the two - 2 pin connectors which are OBD1 knock sensors.

[alpinescott]

that is not an OBD1 knock sensor!

In the TIS link they posted, it is.
