knock sensor testing

Hi guys,

i have the two knock sensors aside the motor (LS2 in a Corvette C5).
If they wouldn`t be connected right or if they wouldn`t work or work correct, would i get a PÜCM code and what code, or is there no security testing for them?

A sensor may be bad and not trip a DTC
If they aren't connected they will trip a DTC code for sure

Hmm and what is the best way to Check? What DTC would show up?
Thank you

View the knock sensor counts on a scantool while you tap the front of the heads with some object (like a wrench).
