Diagnosis Procedure
- CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE POSITION SENSOR POWER SUPPLY
- Turn ignition switch OFF.
- Disconnect intake valve manifold runner control valve position sensor harness connector.
- Turn ignition switch ON.
- Check the voltage between intake valve manifold runner control valve position sensor harness connector.
Intake manifold runner control valve position sensor Voltage (Approx.) Connector + - Terminal F29 1 3 5 V Is the inspection result normal?
YES: GO TO 6.
NO: GO TO 2.
- CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE POSITION SENSOR POWER SUPPLY CIRCUIT
Check the voltage between intake valve manifold runner control valve position sensor harness connector and ground.
+ - Voltage (Approx.) Intake manifold runner control valve position sensor Connector Terminal F29 1 Ground 5 V Is the inspection result normal?
YES: GO TO 4.
NO: GO TO 3.
- CHECK SENSOR POWER SUPPLY 2 CIRCUIT
Check sensor power supply 2 circuit. Refer to "DIAGNOSIS PROCEDURE ".
Is inspection result normal?
YES: Perform the trouble diagnosis for power supply circuit.
NO: Repair or replace error-detected parts.
- CHECK ECM GROUND CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
