Inspection Procedure

HINT:

Read freeze frame data using the Techstream. Freeze frame data records the engine condition 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.

  1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2119) 
    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream ON.
    4. Enter the following menus: Powertrain/Engine/Trouble Codes.
    5. Read DTCs.

    P2119 A
    P2119 and other DTCs B

    HINT:

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

    B: GO TO DTC CHART  (See DIAGNOSTIC TROUBLE CODE CHART )

    A: Go to Next Step 

  2. CHECK WHETHER DTC OUTPUT RECURS (DTC P2119) 
    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream ON.
    4. Clear DTCs (see DTC CHECK/CLEAR ).
    5. Allow the engine to idle for 15 seconds.
      CAUTION: Exercise extreme care and take precautions at procedure "A" and "B" below. Failure to do so may result in the vehicle unexpectedly rolling away.
    6. Securely apply the parking brake and move the gear selector lever to the D position (Procedure "A").
    7. While depressing the brake pedal securely, fully depress the accelerator pedal for 5 seconds (Procedure "B").
    8. Enter the following menus: Powertrain/Engine/Trouble Codes.
    9. Read DTCs.

      HINT:

      The output voltage of the throttle position sensor can be checked during procedure "B" 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/ETCS/Throttle Position No. 1.

      OK: 

      No DTC output. 

    NG: REPLACE THROTTLE BODY ASSEMBLY  (See REMOVAL )

    OK: END
