1F2-22 M161 ENGINE CONTROLS
KNOCK SENSOR (KS)
YAD1F180
The Knock Sensor (KS) detects abnormal knocking in the engine. The two KS are mounted in the engine block
near the cylinders. The sensors produce an output voltage which increases with the severity of the knock. This
signal is sent to the Engine Control Module (ECM) via a shielded cable. The ECM then adjusts the ignition timing
to reduce the spark knock.
