Knock sensor is basically a microphone/vibration sensor tuned to pick up what it thinks is knock frequency's (uses some weird fast Fourier transform mathematical algorithm thingo to process signal via ECU). Loose bolts , loose engine components crook bearings or rattling exhausts can cause noise/vibration that the sensor/ECU may interpret as knock.

also check the earthing strap/wire to engine block.
