Camshaft Position Sensor Power Supply
Inspection

1. Turn the ignition switch to 'ON' position.

2. Disconnect the camshaft position sensor connector.

3. Measure the voltage between the No.1 and No.3 pin of

camshaft position sensor while the ignition switch is in "ON"
position.

Notice

If the measured value is not within the specified value, check
the cable.

Notice

The signal voltage will be changed in the range of 1.2~1.7V.

Camshaft Position Sensor Output Wave
Inspection

1. Connect the test box to the ECU.

2. Measure the output wave between the ECU terminal No.104

and No.106 using the scanner or the oscilloscope while the
engine speed is at idle.

Notice

Replace the camshaft position sensor if cannot get the
output wave as shown in the figure.

Specified Value

11 - 14 V

Specified Value

1.2 - 1.7 V

Camshaft Position Sensor Signal Voltage
Inspection

1. Connect the test box to the ECU.

2. Measure the voltage between the ECU terminal No.11 and

No.106 while the engine speed is at idle.
