DESCRIPTION

The ECM activates 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, engine coolant temperature, intake air temperature and other conditions.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory

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

(a) The output duty of the intake air control valve actuator is 34% or higher.

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

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

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

  • Intake manifold

  • ECM

 Comes on (Euro-OBD) / Does not come on (Except Euro-OBD) DTC stored
P2010 Intake Manifold Runner Control Circuit High (Bank 1)

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 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 intake air control valve actuator deviates from the standard range, the ECM determines that a malfunction has occurred and stores a DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the ignition switch to ON.

  3. Turn the GTS 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.

  7. Turn the GTS on.

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

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

  10. Wait approximately 10 seconds.

  11. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

  12. Read the pending DTCs.

    Tip:

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

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

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

  14. Input the DTC: P2009 or P2010.

  15. Check the DTC judgment result.

    GTS 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
    Tip:

    • 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.

CAUTION / NOTICE / HINT

Tip:

Read Freeze Frame Data using the GTS. 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.
