Hey guys,

So check engine light came on yesterday. Code PO325 knock sensor bank one. I searched the forum and found something similar for the M272, but mine is an M111. Is this an easy DIY? Any help is appreciated, and thanks.

Hey thanks a lot, just updated my profile too, lol. So I take it the car only has the one knock sensor? It doesn't look too hard to get to, hopefully I am not mistaken.

Yes, has only one bank and one knock sensor.

So just to clarify, is the bank something that needs to be replaced? Or is it just the knock sensor? I am not very mechanically inclined. Apologies. Thanks again.

The bank is where the cylinders reside, for lack of a better way to explain it. You don't need to worry about it.

In a V6 engine, there are two banks of cylinders. \ is one bank, / is the other, and the V is so many degrees - like a 60 degree V6 is the angle of the V or a 90 degree V6..

Make sense? The 4 cylinder only has one "bank".

Ah got it. Thanks for all the help guys. Hopefully it's not too hard to replace, or expensive.

I have replaced my knock sensor 2002 C230 Kompressor and still have the p0325 error code what wrong next? I checked the harness and it's not shorted?

Did you delete the old code?

Could you take some good pictures showing where the knock sensor is? I can't find it. Also, please give step by step instruction as to how you've replaced it. What's the easiest way? Would greatly appreciate it. My car is C230
