How to clean the electronic throttle and why should it be reset after cleaning?

If you don't need to match the cable throttle, you need to match the electronic throttle because:

1, the cable throttle has one more component than the electronic throttle, which is the idle motor. The electronic throttle has no idle motor. When the refueling door is at idle speed, the throttle baffle of the cable is fully closed, and the air required for idle speed is entered by the idle motor;

2. Therefore, the cable throttle has no self-adjustment ability, and it will be completely closed without stepping on it. No matter how much it is turned on, whether it is cleaned or not, the computer always thinks that it will be completely closed without stepping on the throttle, and there is no need to match it;

3. Because the electronic throttle has self-adjusting function, it only needs to be matched after cleaning. Assuming that the throttle opening is 8% when there is no carbon deposit, the throttle will open wider and wider when there is more carbon deposit. Assuming that it reaches 18%, the carbon deposit will be cleared.

4. It is impossible for the cleaned throttle to know that you cleaned the throttle in a short time, so the computer will think that the opening at idle speed is still 18%. Now that the carbon deposit is gone, the throttle valve is unobstructed, and the opening of 18% will lead to excessive intake, increased idle speed or unstable idle speed. Throttle matching is to restore the computer value to the state of 8% idle opening, which means that the computer and throttle are the same, so everything is normal.
