Code P0328 2004 Nissan Maxima Description

The P0328 diagnostic trouble code (DTC) for a 2004 Nissan Maxima indicates a Knock Sensor Circuit High Input in Bank 1. The knock sensor is a crucial component in the engine management system that detects abnormal combustion, often referred to as engine knocking or pinging. When the knock sensor detects these irregularities, it sends a signal to the engine control module (ECM) to adjust the ignition timing and prevent engine damage.
