What is the correct matching method of throttle?

The correct matching method of throttle valve is as follows: 1. Matching of diagnostic equipment: After the throttle valve is replaced, it can be matched by the special diagnostic instrument for automobiles. After entering the system, select the action test, zero the adaptive value several times in a row, start the vehicle and work normally, indicating that the matching is successful. 2. Power-off matching: After changing the throttle, you can disconnect the negative electrode of the battery and wait 1 min for installation. In this process, the original memory of the on-board computer was erased, the factory settings were restored, and the vehicle began to run normally, and the matching was successful. But this method is only applicable to low-grade cars, and high-grade cars cannot be used. 3. Function of the throttle: The throttle is a control valve that controls air to enter the engine. After the gas enters the intake pipe, it is mixed with gasoline to form a combustible mixture, which is burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine.
