Knock Sensor 2 Circuit

What does this mean?

OBD2 Code P0330 GM definition:
A knock sensor tells the engine computer when one or more of your engine’s cylinders are “knocking”, that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn’t knock. If your knock sensor wasn’t operating properly, so that it was always indicating a knock, the engine computer’s response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block. This P0330 GM code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325 GM.
