OBD-II Trouble Code Description for P0327 Buick
Knock Sensor 1 Circuit Low
What does this mean?
OBD2 Code P0327 Buick 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 Buick DTC. This P0327 Buick code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325 Buick, P0326 Buick, P0328 Buick, P0329 Buick, P0330 Buick, P0331 Buick, P0332 Buick, P0333 Buick, and P0334 Buick.
