OBD-II Trouble Code Description for P0327 Isuzu

Knock Sensor 1 Circuit Low

What does this mean?

OBD2 Code P0327 Isuzu 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 #1 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0327 Isuzu DTC. This P0327 Isuzu code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325 Isuzu, P0326 Isuzu, P0328 Isuzu, P0329 Isuzu, P0330 Isuzu, P0331 Isuzu, P0332 Isuzu, P0333 Isuzu, and P0334 Isuzu.
