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.TERMINALS VOLTAGE REFERENCE
DTC IVT control solenoid valve Ground Voltage Bank Connector Terminal P0075 1 F28 2 Ground Battery voltage P0081 2 F29 2
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.TERMINALS CONTINUITY REFERENCE
DTC IVT control solenoid valve ECM Continuity Bank Connector Terminal Connector Terminal P0075 1 F28 1 F101 18 Existed P0081 2 F29 1 29 - Also check harness for short to ground and short to power.
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.
- CHECK INTERMITTENT INCIDENT
Refer to "INTERMITTENT INCIDENT ".
