Knock sensor 1 (bank 1) is mounted on the engine block and detects engine knocking. The vibrations caused by the knocking are converted into electrical signals through the piezo ceramic element. The powertrain control module (PCM) controls the ignition timing based on the electrical signal. If the signal from knock sensor 1 (bank 1) is a specified voltage for a set time, the PCM detects a malfunction and stores a DTC.
