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

         If any friction noise exists, replace the throttle body assembly.

   2. Check the throttle position sensor.

      
      

      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON and turn the GTS on.

      3. Enter the following menus: Powertrain / Engine and ECT / Data List / All Data /Throttle Position No. 1 and Throttle Position No. 2.

         
         Powertrain > Engine and ECT > Data List

         Tester Display
         Throttle Position No.1
         Throttle Position No.2

      4. When the throttle valve is fully open, check that the Throttle Sensor Position value is within the specification.

         Tester Display Specified Condition Throttle Sensor Position 60% or higher

         Note

         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 assembly.
