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 tumble control valve, which opens and closes the tumble control valve. 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 tumble control valve is 100%.

(b) The current of the DC motor for the tumble control valve is below 0.35 A.

  • Open or short in DC motor for tumble control valve circuit

  • Intake manifold (DC motor for tumble control valve)

  • ECM
P2010

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

(a) The motor drive IC is overcurrent.

(b) The motor drive IC overheats.

INSPECTION PROCEDURE

Tech Tips

Read freeze frame data using the intelligent tester. 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 AIR CONTROL VALVE ACTUATOR (FOR TUMBLE CONTROL VALVE)


    1. Inspect the intake air control valve actuator Click here.


    NG

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

    OK

  2. INSPECT INTAKE MANIFOLD (TUMBLE CONTROL VALVE OPERATION)


    1. Inspect the intake manifold 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 (Check for Open):
      Tester Connection Condition Specified Condition
      D44-3 (IA1-) - b4-4 (M-) Always Below 1 Ω
      D44-4 (IA1+) - b4-5 (M+) Always Below 1 Ω
      Standard Resistance (Check for Short):
      Tester Connection Condition Specified Condition
      D44-3 (IA1-) or b4-4 (M-) - Body ground Always 10 kΩ or higher
      D44-4 (IA1+) or b4-5 (M+) - 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

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


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the tester on.

    4. Clear the DTCs Click here.

    5. Turn the engine switch off.

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

    7. Enter the following menus: Powertrain / Engine / Data List / 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 / DTC.

    11. Read the DTCs.
