SFI SYSTEM, Diagnostic DTC:P2009, P2010

DTC Code DTC Name
P2009 Intake Manifold Runner Control Circuit Low (Bank 1)
P2010 Intake Manifold Runner Control Circuit High (Bank 1)

DESCRIPTION

The ECM activates the DC motor for the intake air control valve actuator (for tumble control valve), which opens and closes the Tumble Control Valve (TCV). The ECM activates the DC motor based on engine speed, coolant temperature, intake air temperature and other conditions.

DTC No. DTC Detection Condition Trouble Area
P2009

Both of the following conditions continue for 1 second (1 trip detection logic).

(a) The output duty of the DC motor for the intake air control valve actuator is 100% or higher.

(b) The current of the DC motor for the intake air control valve actuator is less than 0.35 A.

  • Open or short in DC motor for intake air control valve actuator (for tumble control valve) circuit

  • Intake air control valve actuator (for tumble control valve)

  • Intake Manifold

  • ECM
P2010

Either of the following conditions continues for 6 times or more (1 trip detection logic).

(a) The motor drive IC has overcurrent.

(b) The motor drive IC overheats.

  • Open or short in DC motor for intake air control valve actuator (for tumble control valve) circuit

  • Intake air control valve actuator (for tumble control valve)

  • Intake Manifold

  • ECM

MONITOR DESCRIPTION

When the voltage of the DC motor deviates from the standard range, the ECM determines that a malfunction has occurred and stores a DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the intelligent tester to the DLC3.

  2. Turn the ignition switch to ON.

  3. Turn the tester on.

  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  5. Turn the ignition switch off and wait for at least 30 seconds.

  6. Turn the ignition switch to ON and turn the tester on.

  7. Enter the following menus: Powertrain / Engine and ECT / Data List / All Data / Coolant Temp.

  8. Check that the engine coolant temperature is 60°C (140°F) or higher.

  9. Wait approximately 10 seconds.

  10. Enter the following menus: Powertrain / Engine and ECT / DTC.

  11. Read the pending DTCs.

    Tech Tips


    • If a pending DTC is output, the system is malfunctioning.

    • If a pending DTC is not output, perform the following procedure.

  12. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

  13. Input the DTC: P2009 or P2010.

  14. Check the DTC judgment result.

    Tester Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

INSPECTION PROCEDURE

Tech Tips

Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. INSPECT INTAKE AIR CONTROL VALVE ACTUATOR (FOR TUMBLE CONTROL VALVE)


    1. Inspect the intake air control valve actuator (for tumble control valve) Click here.


    NG

    REPLACE INTAKE AIR CONTROL VALVE ACTUATOR (FOR TUMBLE CONTROL VALVE) Click here

    OK

  2. INSPECT INTAKE MANIFOLD (TROUBLE CONTROL VALVE OPERATION)


    1. Inspect the intake manifold for the tumble control valve operation Click here.


    NG

    REPLACE INTAKE MANIFOLD Click here

    OK

  3. CHECK HARNESS AND CONNECTOR (ECM - INTAKE AIR CONTROL VALVE ACTUATOR)


    1. Disconnect the ECM connector.

    2. Disconnect the intake air control valve actuator connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      Y4-4 (M-) - E26-21 (IA1-) Always Below 1 Ω
      Y4-5 (M+) - E26-22 (IA1+) Always Below 1 Ω
      Y4-4 (M-) or E26-21 (IA1-) - Body ground Always 10 kΩ or higher
      Y4-5 (M+) or E26-22 (IA1+) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  4. CHECK WHETHER DTC OUTPUT RECURS (DTC P2009 OR P2010)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the tester on.

    4. Clear the DTCs Click here.

    5. Turn the ignition switch off and wait for at least 30 seconds.

    6. Turn the ignition switch to ON.

    7. Turn the tester on.

    8. Wait approximately 10 seconds.

    9. Enter the following menus: Powertrain / Engine and ECT / DTC.

    10. Read the DTCs.
