Pic. 2.23. Throttle assembly: 1 - throttle actuator motor; 2 - throttle valve; 3 - throttle return spring; 4 - throttle position sensor
The use of ETCS-i without mechanical linkage provided excellent throttle control. A DC motor with excellent response and minimum power consumption is used for throttle control. The ECM in standby mode controls the throttle motor current to control the throttle opening angle.
