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.
Specified Value
1 ~ 1.5 A
Notice: If the measured value is not within the specified value, check the cable.

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.

Inspection the ECM
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 and terminal pin No. 115 and No.
114 using a multimeter.
Specified Value
> 10 MΩ
Notice: Replace the KS if the measured values is out of the specified values. Check the connector and wire connec-
tion between ECM and the KS if the measured values are normal.
