Crankshaft Position Sensor Resistance
Inspection

1. Disconnect the coupling "E" of ECU while the ignition switch

is in "OFF" position.

2. Measure the resistance between the coupling terminal pin

No.99 and No.100 using a multimeter.

Notice

Measure the insulator resistance of the crankshaft position
sensor if out of the specified value.

Crankshaft Position Sensor Output Wave
Inspection

1. Connect the test box to the ECU.

2.  Measure the output wave between the ECU terminals No.99

and No.100 using the scanner or the oscilloscope while
engine cranking (starter motor activated).

Notice

Check the segment or crankshaft position sensor and air
gap if cannot get the output wave as shown in the figure.

Specified Value

1050 - 1400 

Ω

Specified Value

> 20k

Ω

Crankshaft Position Sensor Insulator Resistance
Inspection

1. Disconnect the engine coupling from ECU while the ignition

switch is in "OFF" position.

2. Measure the resistance between the coupling terminal pin

No.100 and No.69.

Notice

Measure the check and ground terminal of the crankshaft
position sensor if out of the specified value.

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.

HOT FILM AIR MASS (HFM) SENSOR

1 Housing
2 Protector Net
3 Electronic Housing

Removal & Installation Procedure

1. Turn the HFM sensor coupling in the direction shown in the

figure in the right so that it gets separated from the contact
surface.

Notice

Make sure the HFM sensor coupling connects completely
with the contact surface Installation.

2. Remove the clip with a screw driver.

3. Pry off two tensioning clamps.

4. Remove the HFM sensor.

5. Installation should follow the removal procedure in the

reverse order.
