Throttle control actuator component visual inspection

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnect intake hose connected to throttle control actuator.

(3)

Check if throttle control actuator is contaminated with carbon fraction.

(4)

Check if throttle flap moves smoothly as touching it with hand (perform this process at IG KEY "OFF" state.)

※ Check if abnormal noise, valve shaft stuck, too much wear are detected.

1)

Specification : Flap moves smoothly and carbon fraction, too much wear, abnormal noise are not detected.

(5)

Is throttle control actuator is OK after performing visual inspection?

YES

a.

Go to "2. Throttle control actuator operating test" as follows.

NO

a.

If same symptom is detected after clear carbon fraction up, replace throttle control actuator and go to "Verification of Vehicle Repair".
