Code P0328 MINI Description

The P0328 MINI code indicates that there is a high input signal from knock sensor 1 in the engine control module (ECM). The knock sensor is responsible for detecting abnormal combustion in the engine, such as knocking or pinging, and signaling the ECM to adjust the ignition timing to prevent engine damage. When the knock sensor detects a knock, it sends a signal to the ECM to retard the ignition timing. However, if the knock sensor circuit has a high input signal, it may falsely indicate knocking or pinging when none is present, leading to incorrect adjustments in the ignition timing.
