2004 Tahoe: V..knock sensor (low voltage) bank..sensor cause

Resolved Question:

I have a 2004 Tahoe V-8 code P0332 for knock sensor (low voltage) bank 2. Can anything other than the sensor cause this?
I would hate to change the sensors and have something else easier to fix. I really don't hear any ping or knock. seems to be
running just fine. Thanks Bob

These vehicles have alot of problems with wiring to knock sensors. Disconnect the knock sensor pigtail harness on the back of the intake and check for 100K ohms resistance to ground on both sensors. If off replace knock sensor, if good replace wiring as needed. Let me know if you have questions, thanks.
