Knock Sensors..frustrated! Need help...

[Roccomac]

2002 Tahoe
I recently pulled a P0332 code for rear bank knock sensor low or no connectivity after Check Engine Light came on. I did the TSB on it replacing both sensors(rear one was corroded) and replaced wiring harness...the light comes back on every time for same thing. I have check connections tried bypassing, etc. Light will not go off...what to do next? Can you test the sensors without taking off intake again? Any help appriciated!

Did you clear the code? I know I was getting the same code, and cleared mine, and it has not been back since. It took a couple times. I think the connection may have gotten wet do to engine washing with mine.

Check the harness after the plug to make sure its not damaged...
