Camshaft Actuator Current Consumption Inspection
1. Run the engine to reach the coolant temperature above 70 ° C.
2. Increase the engine rpm up to 2000 rpm
3. Measure the current between the No. 1 and No. 2 pin of the camshaft actuator connector.

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.

Circuit Description
The KS system is used to detect engine detonation, allowing the ECM to retard the ignition control spark timing
based on the KS signal being received. The KS signal’s amplitude and frequency depend upon the amount of
knock being experienced. The ECM monitors the KS signal and can diagnose the KS sensor and circuitry.
Knock Sensor Resistance Inspection
1. Disconnect the coupling from ECM while the ignition switch is in “OFF” position.
2. Measure the resistance between the coupling terminal pin No. 118 and No. 117 using a multimeter.
