P2119 ELECTRIC THROTTLE CONTROL ACTUATOR





Description
Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The throttle position sensor detects the throttle valve position, and feeds the voltage signal to the ECM. The
ECM judges the current opening angle of the throttle valve and controls the throttle valve opening angle in response to driving conditions via the throttle control motor.

2. Remove the intake air duct.





3. Check if foreign matter is caught between the throttle valve (1) and the housing.
- Electric throttle control actuator (2)
Is the inspection result normal?
YES - GO TO 2.
NO - Remove the foreign matter and clean the electric throttle control actuator inside.
2.REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR
1. Replace electric throttle control actuator. Exploded View.
2. Perform P1225.
- INSPECTION END
