Knock Sensor: Description and Operation
-
The knock sensor is installed on the cylinder block, and senses knocking signals.
-
This knock sensor is a piezo-electric type which converts knocking vibrations into electric signals.
-
It consists of a piezo-electric element, weight, and case. If knocking occurs in the engine, the weight in the case moves causing the piezo-electric
element to generate a voltage.
-
The knock sensor is connected to the bulkhead harness through the knock sensor harness.
