What is the reason why landwind x6 Diesel 2.5 turns off the air flow sensor to speed up?

It is initially suspected that it is a problem with the air flow sensor.

What happens when the air flow sensor is unplugged? The air flow meter will not cause engine jitter.

It will lead to poor acceleration, fuel consumption and excessive exhaust gas.

Air flow sensor, also known as air flow meter, is one of the important sensors of EFI engine. It converts the intake air flow into an electrical signal and sends it to the electronic control unit (ECU). As one of the basic signals to determine fuel injection, it is a sensor to measure the intake flow of the engine.

In order to obtain the best mixture concentration under various working conditions, the electronically controlled gasoline injection engine must correctly measure the intake air entering the engine at each moment, which is the main basis for ECU to calculate (control) the fuel injection quantity. If the air flow sensor or circuit fails, the ECU can't get the correct intake signal, so it can't control the fuel injection normally, which will cause the mixture to be too rich or too lean and make the engine run abnormally. There are many types of air flow sensors in electronically controlled gasoline injection system. Common air flow sensors can be divided into vane (wing plate) type, core measuring type, hot wire type, hot film type, Karman vortex street type and so on according to their structural types.
