Why doesn't the sign 307 change the throttle reset?

Attempt to initialize the throttle valve: After the key is turned to the key attachment position for 30s, after hearing the sound of "rushing" from the front engine room, turn the key to the fully closed state. 1 min later, turn the key to the accessory position again, and at the same time, press the accelerator to the bottom and wait for 30s, thus completing the initialization of the accelerator.

Throttle is used to control air intake. The throttle actually controls the throttle and then adjusts the fuel injection quantity according to the throttle. If the throttle valve is dirty, the efficiency will be reduced and the computer will make some adjustments to match it.

After cleaning the throttle valve, it will not match the program that the computer has formed. Initialize the throttle as soon as you get the car, and restore the control program and parameters to the original state. Mismatch will lead to power failure, jitter and even engine alarm. This cleaning is usually done at least once every 30,000 kilometers. Generally, cleaning and matching can be completed within 4 s. If you need to clean and re-match yourself, then you need this self-operated program!
