Code P0332 Cadillac Description
The P0332 diagnostic trouble code (DTC) for Cadillac vehicles indicates that there is a low voltage condition in the knock sensor circuit of Bank 2. Knock sensors are crucial components that detect abnormal engine noise, known as knocking or pinging, which can indicate engine timing issues. When the knock sensor detects these noises, it sends a signal to the engine control module (ECM) to adjust the ignition timing to prevent engine damage. A low voltage reading from the knock sensor can lead to poor engine performance, reduced fuel efficiency, and potential engine damage if left unresolved.
