DTC DETECTION LOGIC
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 ProcedureINFOID:0000000001162679
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 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.

DTC DETECTION LOGIC
NOTE:
Priorities when dealing with a number of DTCs:
If DTC P2610 is displayed with other DTC, first perform the trouble diagnosis for the other DTC.
Special notes:
- The engine only stops after the ignition is switched off.
Diagnosis ProcedureINFOID:0000000001162683
1.CHECK INTAKE AIR DUCT
Check that intake air duct is not obstructed.
Is the inspection result normal?
Yes >> Repair or replace.
No >> GO TO 2.
2.CHECK VACUUM PUMP
Check vacuum pump.
Is the inspection result normal?
Yes >> Repair or replace.
No >> GO TO 3.
3.CHECK TURBOCHARGER
Check turbocharger.
Is the inspection result normal?
Yes >> Repair or replace.
No >> GO TO 4.
4.CHECK TURBOCHARGER BOOST CONTROL SOLENOID VALVE
Refer to EC-1116, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 5.
NO >> Replace turbocharger boost control solenoid valve.
5.CHECK THROTTLE CONTROL MOTOR
Refer to EC-1188, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 6.
NO >> Replace turbocharger boost sensor.
6.CHECK FUEL INJECTOR
Refer to EC-1142, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 7.
NO >> Replace fuel injector.
