Code P0328 2006 Nissan Sentra Description

The P0328 code indicates that there is a high input signal coming from the knock sensor circuit in Bank 1 of the 2006 Nissan Sentra. The knock sensor is responsible for detecting abnormal engine noise caused by detonation or pre-ignition. When the sensor detects a knock, it sends a signal to the engine control module (ECM) to adjust the ignition timing to prevent engine damage. A high input signal typically means that the sensor is detecting a knock when there is none, which can lead to incorrect adjustments in the ignition timing and affect the vehicle's performance.
