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
1.2~1.7v
Notice:The signal voltagewill 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 whileengine speed is at idle.
Notice:Replace the CAM sensor if cannot get the out-
put wave as shown in the figure.
KAA1F0O0
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.

Battery Voltage Correction Mode
When battery voltage is low, the ECM can compensate for a weak spark delivered by the ignition module by using the
following methods:
DIncreasing the fuel injector pulse width.
DIncreasing the idle speed rpm.
DIncreasing the ignition dwell time.
Fuel Cut- Off Mode
No fuel is delivered by the fuel injectors when the ignition is off. This prevents dieseling or engine run -- on. Also, the fuel
is not delivered if there are no reference pulses received from the CKP sensor. This prevents flooding.

Notice:Prepare the beaker for taking the fuel.
4. Connect the shop made cable to the injector with a firing order.
5. Connect the other end of shop made cable to the positive battery cable and negative battery cable.
6. Turn the ignition switch ON.
7. Check the injector for normal spray pattern as shown in the figure. Check injector for leaks or later drop
Injector Resistance Inspection
1. Turn the ignition switch OFF.
2. Remove the fuel injector connectors.
3. Measure the fuel injector coil resistance using a multimeter.
Specified Value
14 ~ 17Ω
Notice:Replace the fuel injector if the measured value is out of the specified values. Check the connector and wire
connection between the ECM and the injector if the measured values are normal.
Injector Pulse Width Inspection
1. Turn the ignition switch OFF.
2. Install the scan tool.
3. Turn the ignition switch ON.
4. Monitor the “INJECTION TIME” with a scan tool.
