THROTTLE BODY ON-VEHICLE INSPECTION


  1. INSPECT THROTTLE 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 any friction noise exists, replace the throttle 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 and ECT / Data List / Throttle Sensor Position.

      5. When the throttle valve is fully opened, check that the value of "Throttle Sensor Position" is within the specification.

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

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

        Note


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

        • Fully depress the accelerator pedal.
