Code P0328 2012 Nissan Pathfinder Description

The P0328 diagnostic trouble code (DTC) for a 2012 Nissan Pathfinder indicates a Knock Sensor Circuit High Input in Bank 1. This means that the engine control module (ECM) has detected a higher than normal voltage signal from the knock sensor in the first bank of cylinders. The knock sensor is a crucial component in the engine management system that detects abnormal combustion, often referred to as engine knock or detonation. When the knock sensor detects these abnormal vibrations, it sends a signal to the ECM to adjust the ignition timing to prevent engine damage.
