THROTTLE BODY ON-VEHICLE INSPECTION


  1. INSPECT THROTTLE WITH MOTOR BODY ASSEMBLY


    1. Check the throttle control motor operating sound.


      1. Turn the engine switch on (IG).

      2. When depressing the accelerator pedal, check the operating sound of the motor. Make sure that no friction noises are emitted from the motor.

        If friction noise exists, replace the throttle with motor body assembly.

    2. Check the throttle position sensor.


      1. Connect the intelligent tester to the DLC3.

      2. Turn the engine switch on (IG).

      3. Turn the intelligent tester on.

      4. Enter the following menus: Powertrain / Engine / Data List/ All Data / Throttle Sensor Position.

      5. Depress the accelerator pedal. When the throttle valve is fully open, check that the Throttle Sensor Position value is within the specification.

        Standard Throttle Valve Opening Percentage
        Tester Display Specified Condition
        Throttle Sensor Position 60% or more

        Note


        • When checking the throttle valve opening percentage, the shift lever should be in neutral.

        • Fully depress the accelerator pedal.

        If the percentage is less than 60%, replace the throttle with motor body assembly.
