Diagnosis Procedure
- CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Disconnect intake valve timing control solenoid valve harness connector.
- Turn ignition switch ON.
- Check the voltage between intake valve timing control solenoid valve harness connector and ground.DTC CHART

Is the inspection result normal?
YES: GO TO 3.
NO: GO TO 2.
- DETECT MALFUNCTIONING PART
Check the following.
- Harness connectors E3, F1
- Harness for open or short between intake valve timing control solenoid valve and IPDM E/R
Repair open circuit or short to ground or short to power in harness or connectors.
- CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between intake valve timing control solenoid valve harness connector and ECM harness connector.DTC CHART

Is the inspection result normal?
YES: GO TO 4.
NO: Repair open circuit or short to ground or short to power in harness or connectors.
- CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
Refer to "COMPONENT INSPECTION ".
Is the inspection result normal?
YES: GO TO 5.
NO: Replace malfunctioning intake valve timing control solenoid valve.
