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 intake air control valve actuator for Swirl Control Valve (SCV), which opens and closes swirl control valve. The ECM activates the DC motor based on engine speed, coolant temperature, engine load signals and other conditions.

DTC No. DTC Detection Condition Trouble Area
P2009

Both of the following conditions continue for 0.5 seconds (1 trip detection logic):

(a) The output duty of the intake air control valve actuator for swirl control valve is 100% or more.

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

  • Open or short in intake air control valve actuator for swirl control valve circuit

  • Intake manifold (intake air control valve actuator for swirl control valve)

  • 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.

MONITOR DESCRIPTION

When the voltage of the DC motor (intake air control valve actuator) deviates from the standard range, the ECM determines that a malfunction has occurred and sets a DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG).

  3. Turn the GTS on.

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

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

  6. Turn the engine switch on (IG) and turn the GTS on.

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

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

  9. Wait approximately 10 seconds.

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

  11. Read 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.

    Techstream 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.

INSPECTION PROCEDURE

Tech Tips

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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 MANIFOLD (SWIRL CONTROL VALVE OPERATION)


    1. Inspect the intake manifold Click here.


    NG

    REPLACE INTAKE MANIFOLD Click here

    OK

  2. 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
      F3-6 (IA1-) - F42-2 Always Below 1 Ω
      F3-7 (IA1+) - F42-1 Always Below 1 Ω
      F3-6 (IA1-) or F42-2 - Body ground Always 10 kΩ or higher
      F3-7 (IA1+) or F42-1 - body ground Always 10 kΩ or higher

    4. Reconnect the ECM connector.

    5. Reconnect the intake air control valve actuator connector.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

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


    1. Connect GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Clear the DTCs Click here.

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

    6. Turn the engine switch on (IG).

    7. Turn the GTS on.

    8. Wait approximately 10 seconds.

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

    10. Read the DTCs.
