    DIAGNOSTIC TROUBLE CODE CHART [08/2017 - 08/2018]

    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 [08/2015 - 08/2018] ).

    Result: 

    B 

    See step  4

    Result: 

    A 

    See step  3

  3. INSPECT THROTTLE BODY ASSEMBLY (RESISTANCE OF THROTTLE ACTUATOR)

    Result: 

    NG 

    See step  7
