THROTTLE BODY ON-VEHICLE INSPECTION

PROCEDURE

1. CHECK THROTTLE BODY WITH MOTOR ASSEMBLY

   
   

   1. Check the throttle actuator operating sounds.

      
      

      1. Turn the ignition switch to ON.

      2. When depressing the accelerator pedal, check the operating sound of the running motor. Make sure that no friction noises are emitted from the throttle actuator. If friction noise exists, replace the throttle body with motor 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 / Data List / Throttle Sensor Position.

         
         Powertrain > Engine > 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

         Tech Tips

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

         
         

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