Code P0328 2007 Nissan Pathfinder Description

The P0328 diagnostic trouble code (DTC) for a 2007 Nissan Pathfinder 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, commonly known as engine knock or detonation. When the knock sensor detects these vibrations, it sends a signal to the engine control module (ECM) to adjust the ignition timing to prevent engine damage.
