Code P0328 2006 Scion xB Description

The P0328 diagnostic trouble code (DTC) for a 2006 Scion xB indicates that there is a high input signal detected from Knock Sensor 1 Circuit. The knock sensor is a crucial component in the engine management system, responsible for detecting abnormal combustion in the engine. When the knock sensor detects unusual vibrations or noises that suggest pre-ignition or detonation, it sends a signal to the engine control module (ECM) to adjust the ignition timing to prevent engine damage.
