Knock Sensor: Description and Operation
Knock Sensor (KS) Operation
Knock Sensor (KS) Sensor
The Electronic Spark Control (ESC) Knock sensor detects abnormal vibration (spark knocking) in the engine. The sensor is mounted in the engine block
near the cylinders. The sensor produces an AC output voltage which increases with the severity of the knock. This signal voltage inputs to the
ECM/PCM. The ECM/PCM then adjusts the Electronic Spark Timing (EST) to reduce spark knocking.
