Electric Throttle Control Actuator
FUNCTIONS WITHIN THE SYSTEM
The ECM transmits the control signal to the electronically controlled throttle and controls the throttle position according to the driving conditions.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
The electric throttle control actuator consists of throttle body, throttle valve, throttle control motor and throttle position sensor.
INDIVIDUAL OPERATION
Throttle Motor
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
Throttle Position Sensor
The throttle position sensor has two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals.
COMPONENT LOCATION
The electric throttle valve actuator is installed beside the intake manifold collector.
