Camshaft Position Sensor Output
Wave Inspection
1. Measure the output wave between the ECM terminals
No. 104 and No. 106 using the scan tool or the
oscilloscope while engine speed is at idle.
Notice
Replace the CAM sensor if cannot get the out-put
wave as shown in the figure.
Camshaft Position Sensor Power
Supply Inspection
1. Disconnect the CMP sensor Connector.
2. Measure the voltage between the No. 1and No. 3 pin of
the CMP sensor connector while the ignition switch is in
“ON” position.
Notice
If the measured value is not within the specified value,
check the cable.
Specified value
11 ~ 14V

CAMSHAFT ACTUATOR
When the engine is running, the camshaft actuator rotates the intake camshaft hydraulically and mechanically relative
to the camshaft sprocket by 32° crank angle to the “advanced” position and back to the “retard” position.
The camshaft actuator is actuated electro-mechanically by the Engine Control Module (ECM).
The positioning time of apporx. 1 second is dependent on the engine oil pressure at the camshaft actuator and on the oil
viscosity and oil temperature, respectively.
The camshaft indicator on the camshaft sprocket provides the camshaft rotational speed to the position sensor as an
input parameter for the engine ignition control unit.

KNOCK SENSOR (KS)
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.
