Eventually this turns on the check engine light and sets the codes P0332 and P0327. Note that often either one or the other code will set. Regardless if one or both codes are set, not only should the two original knock sensors be replaced, but you should also replace the harness.

Where is the knock sensor on a Chevy 6.0?
In Chevy 6.0 engines the knock sensor sits underneath the intake manifold in the lifter section.

Engine knock happens when a gasoline burns unevenly in a cylinder.

Why does my Vortec 6000 make a knocking noise?
If you get a check engine light and codes for engine knock on your 6.0L vortec, it could be actual engine knock.
