1F2 -- 32 M161 ENGINE CONTROLS DAEWOO MY_2000 KNOCK SENSOR (KS) YAA1F320 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. |
