Q: What does code P1322 mean?

Knock Sensor 3 Circuit High Input. P1322 on Volkswagen vehicles means the engine control module (ECM) has detected an abnormally high voltage on the signal circuit of knock sensor 3, which is typically the sensor monitoring the cylinder bank furthest from the front of the engine. The ECM expects the sensor to produce a small, fluctuating voltage in response to engine vibration, and a high input tells the module that the circuit is open, shorted to voltage, or the sensor itself has failed.
