Knock Sensor: Description and Operation

Component Description

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block
is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the ECM.
