1 Crankshaft Position Sensor
2 Bolt (M6 X 14)........................................ 9 -11Nm
CRANKSHAFT POSITION SENSOR
Removal & Installation Procedure
1. Disconnect the wiring connector at the crankshaft position
sensor.
2. Unscrew the bolt and remove the crankshaft position sensor unit. Installation Notice
3. Installation should follow the removal procedure in the reverse order. 3 Segment
4 Flywheel
Tightening Torque 9 -11Nm

1F1-66 M162 ENGINE CONTROLS Crankshaft Position Sensor Resistance Inspection
1. Disconnect the coupling "E" of ECU while the ignition switchis 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
Specified Value > 20k
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
1 Bolt (M6 X 14)......................................... 9-11Nm
2 Camshaft Position Sensor
Removal & Installation Procedure
1. Disconnect the wiring connector from the camshaft position sensor.
2. Unscrew the bolt (2) and remove the camshaft position sensor. Installation Notice 3 Shim
5 O-ring
Tightening Torque 9 - 11 Nm
3. Check the clearance and replace the shim if necessary.
4. Check the O-ring for damage and replace it if necessary.
5. Installation should follow the removal procedure in the
reverse order.

1F1-68 M162 ENGINE CONTROLS 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 ofcamshaft 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 andNo.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. 4 Connector
