On a 2004 Chevrolet Tahoe, do the codes P0327 & P0332 indicate which knock sensor is bad?

Question

On a 2004 Chevrolet Tahoe 5.3L, I got a P0332. I replaced both the knock sensors and the wiring harness. Now I am getting a P0327 code. Any suggestions would be most appreciated. Thanks. I hate the thought of going back in again.

Answer 1

P0332 Knock sensor 2 circuit low input

P0327 Knock sensor 1 circuit low input

P0327 referrs to the front knock sensor and P0327 referrs to the rear knock sensor, If the knock sensor was dropped during shipment or storage it can develop a failed knock sensor. The knock sensor due to its location tends to have debris it housing should be cleaned, use a shop air or a vacuum cleaner, and when the knock sensor is installed there is a TSB about water intrusion where its cover should have silicone applied to protect it from water intrusion
