Knock Sensor: Description and Operation

KS

Component Description

The knock sensor (KS) 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.
