Where is the idle motor of Jiefang truck?

Jiefang truck idle motor is on the accelerator. According to relevant data, the throttle body has a bypass passage to provide air when the engine is idling (when the throttle is closed). The pivot of the automatic idle motor extends into the bypass air passage. By adjusting the air flow, the engine controller can adjust the engine idle speed by moving the pivot of the automatic idle motor into and out of the bypass air passage according to the input signals of various sensors. When the ignition key is turned to the on position, the automatic idle motor starts to work. The switch signal is input to ECU to detect whether the engine is idling. At the same time, the instantaneous position of motor is fed back to ECU through motor position sensor.
