D09.41-1183-06
Location
The throttle valve actuator is located on the engine at the right left.
Task
The throttle valve actuator regulates the fresh air quantity and mixes the recirculated exhaust gas with fresh air.
Function
The throttle valve actuator is actuated by the CDI control unit (N3/21) through a pulse width modulated signal (PWM signal) and regulates the fresh air quantity passing through the installed throttle valve. Through connection of the exhaust gas recirculation with the mixing throttle, the suctioned fresh air is mixed with the recirculated exhaust.
