Code P0328 2015 Toyota RAV4 Description
When the P0328 diagnostic trouble code (DTC) is set in a 2015 Toyota RAV4, it indicates that there is a high input signal detected from Knock Sensor 1, which is a crucial component in the engine management system. The knock sensor is responsible for detecting abnormal engine vibrations or knocking noises caused by pre-ignition or detonation, allowing the engine control module (ECM) to adjust ignition timing accordingly. A high input signal from the knock sensor suggests that the sensor is detecting abnormal engine vibrations even when they are not present, potentially leading to incorrect adjustments in ignition timing. This can result in reduced engine performance, fuel economy, and emissions, as well as potential engine damage if left unaddressed.
