Detonation (Knock) Sensor: Description and Operation

Detonation (Knock) Sensor

The detonation sensor is a signal generator that operates when a spark knock occurs in the combustion chambers.  The sensor is mounted in the engine
block where it can detect detonation in any of the cylinders.  The sensor sends a signal to the engine controller indicating that ignition knock (ping) is
occuring.  The engine controller will then adjust the spark advance in order to eliminate the detonation.
