Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

2.
CHECK INTAKE VALVE TIMING CONTROL POSITION SENSOR POWER SUPPLY CIRCUIT
1.
Disconnect intake valve timing control position sensor harness connector.
2.
Turn ignition switch ON.
3.
Check voltage between intake valve timing control position sen-
sor terminal 3 and ground with CONSULT-II or tester.
OK or NG
OK
>> GO TO 4.
NG
>> GO TO 3.
3.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors E108, M15
●
Harness connectors F102, M72
●
Harness for open or short between intake valve timing control position sensor and IPDM E/R
●
Harness for open or short between intake valve timing control position sensor and ECM
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.
CHECK INTAKE VALVE TIMING CONTROL POSITION SENSOR GROUND CIRCUIT FOR OPEN AND
SHORT
1.
Turn ignition switch OFF.
2.
Check harness continuity between intake valve timing control position sensor terminal 1 and ground.
Refer to Wiring Diagram.
3.
Also check harness for short to power.
OK or NG
OK
