Knock Sensor: Description and Operation

The two knock sensors are attached to the cylinder block and sense 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 ECM.
