DTC P2119: Throttle Actuator Control Throttle Body Range / Performance [12/2015 - 08/2016]: Procedure

WARNING: This page is about a different car, the 2016 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2119) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine / Trouble Codes.
    5. Read DTCs.
      RESULT

      Result Proceed to
      DTC P2119 is output A
      DTC P2119 and other DTCs are output B

      HINT: 

      If any DTCs other than P2119 are output, troubleshoot those DTCs first.

    Result: 

    B 

    GO TO DTC CHART 

    (Refer to DIAGNOSTIC TROUBLE CODE CHART [12/2015 - 08/2016] )

    Result: 

    A 

    See step  2

  2. READ VALUE USING TECHSTREAM (THROTTLE POSITION) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Clear DTCs (Refer to DTC CHECK / CLEAR [12/2015 - 08/2016] ).
    5. Turn the ignition switch to off and wait for at least 30 seconds.
    6. Turn the ignition switch to ON.
    7. Enter the following menus: Powertrain / Engine / Data List / Throttle Position No. 1 and Throttle Position Command.
    8. Check the values displayed on the Techstream while fully depressing and releasing the accelerator pedal quickly.
      RESULT

      Result Proceed to
      Throttle Position No. 1 does not change A
      Throttle Position No. 1 changes even a little B

      HINT: 

      As the system changes to fail-safe mode if a DTC is output, when a DTC is output, only use the data up until the time the DTC is stored for confirmation.

    Result: 

    B 

    See step  4

    Result: 

    A 

    See step  3

  3. INSPECT THROTTLE BODY WITH MOTOR ASSEMBLY (RESISTANCE OF THROTTLE ACTUATOR) 
    1. Inspect the throttle body with motor assembly (Refer to INSPECTION [12/2015 - 08/2016] ).

    Result: 

    NG 

    See step  7

    Result: 

    OK 

    See step  4

  4. INSPECT THROTTLE BODY WITH MOTOR ASSEMBLY (VISUALLY CHECK THROTTLE VALVE) 
    1. Check for contamination between the throttle valve and housing. If necessary, clean the throttle body with motor assembly. Also, check that the throttle valve moves smoothly.

      OK

      Throttle valve is not contaminated with foreign objects and moves smoothly.

    Result: 

    NG 

    See step  7

    Result: 

    OK 

    See step  5

  5. READ VALUE USING TECHSTREAM (THROTTLE POSITION) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Clear DTCs (Refer to DTC CHECK / CLEAR [12/2015 - 08/2016] ).
    5. Turn the ignition switch to off and wait for at least 30 seconds.
    6. Turn the ignition switch to ON.
    7. Enter the following menus: Powertrain / Engine / Data List / Throttle Position No. 1, Throttle Position No. 2 and Throttle Position Command.
    8. Check the values displayed on the Techstream while wiggling the ECM wire harness.
    9. Enter the following menus: Powertrain / Engine / Trouble Codes.
    10. Read the DTCs.
      RESULT

      Result Proceed to
      Value in Data List changes when wire harness is wiggled, or DTC is output. A
      Other than above B

    Result: 

    B 

    See step  8

    Result: 

    A 

    See step  6

  6. REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - THROTTLE BODY WITH MOTOR ASSEMBLY) 

    HINT: 

    As the DTC was stored due to a change in the contact resistance of the connector, repair or replace the wire harness or connector (Refer to ELECTRONIC CIRCUIT INSPECTION PROCEDURE [12/2015 - ] ).

    Result: 

    NEXT 

    END 

  7. REPLACE THROTTLE BODY WITH MOTOR ASSEMBLY 
    1. Replace the throttle body with motor assembly (Refer to REMOVAL [12/2015 - 08/2016] ).

      HINT: 

      Perform "Inspection After Repair" after replacing the throttle body with motor assembly (Refer to INITIALIZATION [12/2015 - 08/2016] ).

    Result: 

    NEXT 

    See step  8

  8. CONFIRM WHETHER DTC OUTPUT RECURS (DTC P2119) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Clear the DTCs (Refer to DTC CHECK / CLEAR [12/2015 - 08/2016] ).
    5. Allow the engine to idle for 15 seconds or more.
    6. Fully depress and release the accelerator pedal several times quickly.
    7. Enter the following menus: Powertrain / Engine / Trouble Codes.
    8. Read the DTCs.

      HINT: 

      The output voltage of the throttle position sensor can be checked using the Techstream. Variations in the output voltage indicate that the throttle actuator is in operation. To check the output voltage using the Techstream, enter the following menus: Powertrain / Engine / Data List / Throttle Position No. 1.

      RESULT

      Result Proceed to
      DTC is not output A
      DTC P2119 is output B

    Result: 

    A
