I have not been able to find a source online showing the location of the bank 2 knock sensor. I was able to find diagrams and videos associated with bank 1. Any chance you have access to a diagram or at least can outline the location?

Good afternoon.

The knock sensor for bank 2 is right by the oil filter under the engine. I attached a picture for you to view. It is number 8 in the diagram.
