|P0332 BUICK code description

The Knock Sensor (KS) system monitors both knock sensors in order to determine if detonation is present. If the KS system determines that excessive knock (detonation) is present, the Powertrain Control System (PCM) retards the spark timing based on the signals from the KS system. When knock is present, the KS system voltage input signal to the PCM goes low. The PCM then retards timing until no knock is present.
