Circuit Description
The CMP sensor sends a cam position signal to the ECM. If the cam position signal is lost while the engine is running,
the fuel injection system shifts to a calculated sequential fuel injection mode based on the last fuel injection pulse, and
the engine continuous to run.
Camshaft Position Sensor Signal Voltage Inspection
1. Measure the voltage between the ECM terminal No. 11 and No. 106 while the engine speed is at idle.
Specified Value
1.2 ~ 1.7 v
Notice: The signal voltage will be changed in the range of 1.2 ~ 1.7 v.

Camshaft Position Sensor Output Wave Inspection
1. Measure the output wave between the ECM termi-
nals 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.

Camkshaft Position Sensor Power Supply Inspection
1. Disconnect the CMP sensor Connector.
2. Measure the resistance between the No. 1 and No. 3 pin of the CMP sensor connector while the ignition switch is in
“ON” position.
Specified Value
11 ~ 14 v
Notice: If the measured value is not within the specified value, check the cable.

CAMSHAFT ACTUATOR
YAA1F300
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.
