Detonation Sensor: Description and Operation

    The knock sensor is attached to the cylinder block and senses engine knocking conditions. A knocking vibration from the cylinder block is applied as
pressure to the piezoelectric element. This vibrational pressure is then converted into a voltage signal which is sent to the ECU.
