OBD-II Trouble Code Description for P0332 Suzuki

Knock Sensor 2 Circuit Low

What does this mean?

OBD2 Code P0332 Suzuki 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 on Bank #2 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0332 Suzuki DTC. This P0332 Suzuki code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325 Suzuki, P0326 Suzuki, P0327 Suzuki, P0328 Suzuki, P0329 Suzuki, P0330 Suzuki, P0331 Suzuki, P0333 Suzuki, and P0334 Suzuki.
