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

The DTC becomes present after the engine is started.

• Special notes:
- Engine instability, possibly even stalling.
- Difficult to start engine or even impossible when cold.
- Loss of performance.
- Possible smoke emissions.
• If the DTC is present:
- Malfunction indicator (Red) lights up.

Diagnosis Procedure

INFOID:0000000000970932

1.

CHECK GROUND CONNECTIONS

1.

Turn ignition switch OFF.

2.

Check ground connection E17. Refer to Ground inspection in 

GI-41, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace ground connection.

2.

CHECK EGR VOLUME CONTROL VALVE INSTALLATION

Check that EGR volume control valve is installed properly.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Install EGR volume control valve properly.

3.

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 4.

NO

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

4.

CHECK EGR VOLUME CONTROL VALVE CONTROL POSITION SENSOR GROUND CIRCUIT FOR

DTC No.

P2413 EGR SYSTEM

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 5.

NO

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

5.

CHECK EGR VOLUME CONTROL VALVE CONTROL POSITION SENSOR INPUT CIRCUIT FOR OPEN

AND SHORT

1.

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

2.

Also check harness for short to ground and short to power. 

Is the inspection result normal?

YES

>> GO TO 6.

NO

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

6.

CHECK EGR VOLUME CONTROL VALVE CONTROL MOTOR CIRCUIT

1.

Check harness continuity between the following terminals.

2.

Also check harness for short to ground and short to power. 

Is the inspection result normal?

YES

>> GO TO 7.

NO

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

7.

CHECK EGR VOLUME CONTROL VALVE VISUALLY

1.

Remove the EGR volume control valve

2.

Check if foreign matter is caught between the EGR volume control valve and the housing.

Is the inspection result normal?

YES 

>> GO TO 8.

NO

>> Remove the foreign matter and clean the EGR volume control valve.
