P2006 Error Code Diagnostic Procedure

P2006

Intake Manifold Runner Control Stuck Closed (Bank 1)

DESCRIPTION

The swirl control valve is mounted on the intake manifold. The Vacuum Switching Valve (VSV) for swirl control valve for changes the vacuum to actuate the actuator.
The ECM determines the opening angle of the swirl control valve, and uses the swirl control valve VSV to change the vacuum applied to the actuator’s diaphragm to open and close the swirl control valve.

DTC No. DTC Detection Condition Trouble Area
P2006 When actual intake air volume detected by MAF meter continues to be smaller than volume estimated from boost pressure and intake air temperature sensor, ECM determines that swirl control valve is stuck closed.
(1 trip detection logic)

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, and other data from the time the malfunction occurred.

 

NOTICE:
If the ECM is replaced, the new ECM needs initialization.

 

1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P2006)
  1. Connect the intelligent tester to the DLC3.
  1. Turn the ignition switch ON and turn the intelligent tester ON.
  1. Enter the following menus: Powertrain / Engine / DTC.
  1. Read the DTCs.
    Result:

    Display (DTC Output) Proceed to
    P2006 A
    P2006 and other DTCs B

GO TO RELEVANT DTC CHART
A

 

2.CHECK CONNECTION OF AIR CLEANER HOSE
  1. Check the installation condition of the air cleaner hose.
NG
REPAIR OR REPLACE AIR CLEANER HOSE
OK

 

3.CHECK CONNECTION OF VACUUM HOSE
  1. Check the vacuum hose connection of the swirl control valve system.
NG
REPAIR OR REPLACE VACUUM HOSE
OK

 

4.PERFORM ACTIVE TEST USING VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE (VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE)



A067588E05
  1. Disconnect the vacuum hoses from the VSV for swirl control valve.
  1. Connect the intelligent tester to the DLC3.
  1. Turn the ignition switch ON and turn the tester ON.
  1. Enter the following menus: Powertrain / Engine / Active Test / Activate the VSV for Swirl Control Valve.
  1. Check the operation.

     

    OK:
    When VSV for swirl control valve is ON, air from port E flows out through port F. 
    When VSV for swirl control valve is OFF, air from port E flows out through air filter.

     

NG
Go to step 8
OK

 

5.INSPECT VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE (RESISTANCE)
G036521E01
  1. Disconnect the S9 VSV connector.
  1. Measure the resistance of the VSV.
    Standard resistance:

    Tester Connection Condition Specified Condition
    1 – 2 20°C (68°F) 37 to 44 Ω

     

NG
REPLACE VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE
OK

 

6.CHECK HARNESS AND CONNECTOR (VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE – ECM)
G034916E02
  1. Disconnect the S9 VSV connector.
  1. Disconnect the E8 ECM connector.
  1. Measure the resistance of the wire harness side connectors.
    Standard resistance (Check for open):

    Tester Connection Specified Condition
    S9-1 – E8-15 (SCV) Below 1 Ω
    Standard resistance (Check for short):

    Tester Connection Specified Condition
    S9-1 or E8-15 (SCV) – Body ground 10 kΩ or higher

     

NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK

 

7.CHECK HARNESS AND CONNECTOR (INTEGRATION RELAY (MAIN RELAY) – VACUUM SWITCHING VALVE FOR SWIRL CONTROL VALVE)
G034915E03
  1. Remove the integration relay from the engine room junction block. 
  1. Disconnect the 1J integration relay connector.
  1. Disconnect the S9 VSV connector.
  1. Measure the resistance of the wire harness side connectors.
    Standard resistance (Check for open):

    Tester Connection Specified Condition
    1J-5 – S9-2 Below 1 Ω

     

     

    Standard resistance (Check for short):

    Tester Connection Specified Condition
    1J-5 or S9-2 – Body ground 10 kΩ or higher

     

NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK
REPLACE ECM

8.INSPECT INTAKE MANIFOLD (SWIRL CONTROL VALVE OPERATION)
  1. Inspect intake manifold (swirl control valve) .

 

NG
REPLACE INTAKE MANIFOLD
OK

9.CHECK ELECTRIC EGR CONTROL VALVE ASSEMBLY
  1. Check electric EGR control valve .

 

NG
REPLACE ELECTRIC EGR CONTROL VALVE ASSEMBLY
OK

10.INSPECT MASS AIR FLOW METER
  1. Inspect mass air flow meter .

 

NG
REPLACE MASS AIR FLOW METER
OK

11.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P2008/58)
  1. Connect the intelligent tester to the DLC3.
  1. Turn the ignition switch ON and turn the intelligent tester ON.
  1. Enter the following menus: Powertrain / Engine / DTC.
  1. Read the DTCs.

     

    Result:

    Display (DTC Output) Proceed to
    P2006 A
    No DTC B
