Can Cheng Jing 1.8 displacement electronic throttle adjust idle speed?

You can't use the electronic throttle to increase the idle speed of the car. The idle speed of the electronic throttle can only be adjusted by the engine control system, not manually.

The throttle opening and closing of the electronic throttle is completely controlled by the motor, unlike the traditional throttle which is mechanically controlled by the throttle line between the throttle pedal and the throttle. Whether it is electronic throttle or cable throttle, idle speed is self-adjusting. Due to the influence of carbon deposition, the idle speed will change. Take the electronic throttle as an example. After the throttle is completely released, the electronic throttle will not be completely closed, and there will be a certain gap for air to pass through, which is the air needed for idling. If there is carbon deposit, it will block some gaps and the amount of air entering will be less. If no measures are taken, idling jitter or even flameout will occur. At this time, the engine computer will control the throttle to open a little gap, so that the air intake will be more and the normal idle speed can be maintained. Although the computer can control the throttle to adjust the idle speed, of course, it will not be infinitely adjusted, only a small adjustment range. Adjust it to the limit, or the car will break down.
