Code P0332 2010 Nissan Altima Sedan Description

The diagnostic trouble code P0332 in a 2010 Nissan Altima Sedan indicates a problem with the Knock Sensor 2 Circuit Low Input Bank 2. The knock sensor plays a vital role in the engine management system by detecting abnormal combustion, often referred to as engine knock or detonation. When the knock sensor detects these abnormal vibrations, it sends a signal to the engine control module (ECM) to adjust the ignition timing to prevent engine damage.
