Code P0328 2011 Nissan Pathfinder Description

The P0328 diagnostic trouble code (DTC) for a 2011 Nissan Pathfinder refers to a Knock Sensor Circuit High Input for Bank 1. This code indicates that the engine control module (ECM) has detected a higher than normal signal from the knock sensor located in bank 1 of the engine. The knock sensor is responsible for detecting abnormal vibrations or knocking in the engine, which can be caused by issues such as pre-ignition 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.
