DTC DETECTION LOGIC

NOTE:
• If DTC P0409 is displayed with DTC P0651, first perform trouble diagnosis for DTC P0651. Refer to

EC-1182, "DTC Logic"

.

• Conditions for applying the diagnostic procedure to the stored DTCs:

 The DTC is declared present after the engine started.

• If the DTC is present:
- Malfunction indicator (Yellow) lights up.

Diagnosis Procedure

INFOID:0000000001162624

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

Check ground connection E15. Refer to Ground inspection in 

GI-58, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

CHECK EGR VOLUME CONTROL VALVE CONTROL POSITION SENSOR POWER SUPPLY CIRCUIT

1.

Disconnect EGR volume control valve harness connector.

2.

Turn ignition switch ON.

3.

Check the voltage between EGR volume control valve control position sensor connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.

3.

CHECK EGR VOLUME CONTROL VALVE CONTROL POSITION SENSOR GROUND CIRCUIT FOR

OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between EGR volume control valve control position sensor harness connector and
ECM harness connector.

4.

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.

DTC No.
