Code P0328 2009 Nissan Sentra Description

The P0328 code for a 2009 Nissan Sentra indicates a problem with the knock sensor circuit on Bank 1. The knock sensor is a crucial component in the engine management system, responsible for detecting abnormal combustion, or engine knocking, that can potentially cause damage. When the knock sensor circuit reports a high input signal to the Engine Control Module (ECM), it means that the sensor is detecting excessive vibration or detonation in the engine, which can lead to reduced performance, decreased fuel efficiency, and potential engine damage if not addressed promptly.
