THROTTLE BODY ON-VEHICLE INSPECTION

PROCEDURE

1. CHECK THROTTLE WITH MOTOR BODY ASSEMBLY

   
   

   1. Check the throttle control motor operating sounds.

      
      

      1. Turn the ignition switch to ON.

      2. When pressing the accelerator pedal, check the operating sound of the running 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 GTS to the DLC3.

      2. Turn the ignition switch to ON.

      3. Turn the GTS on.

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

         
         Powertrain > Engine and ECT > Data List

         Tester Display
         Throttle Sensor Position

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

         Standard throttle valve opening percentage
         60% or more

         Note

         When checking the standard throttle valve opening percentage, make sure the shift lever is in N.

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