knock sensor for 2000 blazer

[getblazed00]

Does anybody know if the DTC PO 325 knock sensor 1 circuit malfunction (bank 1 or single sensor) is referring to the drivers side or the passenger side knock sensor? I bought the part already but I don't want to tear down both sides today to fix it.

Any reference to "Bank 1" for knock sensors and oxygen sensors, is always the bank that the #1 spark plug is in.

Welcome on your first post on AF.
Double check that code no.
If you have a code 325 it is not a knock sensor code but rather a knock sensor module code.
Has the pcm/vcm been swapped or changed or opened up.
The knock sensor module is located inside the little cover on the VCM.
Is it in there?
Also clear code and see if it returns.
And check wiring to knock sensors and VCM.
