Knock Sensor 1 Circuit Low

What does this mean?

OBD2 Code P0327 Porsche 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 Porsche DTC. This P0327 Porsche code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325 Porsche, P0326 Porsche, P0328 Porsche, P0329 Porsche, P0330 Porsche, P0331 Porsche, P0332 Porsche, P0333 Porsche, and P0334 Porsche.
