What are the bad rice of air flowmeter?

If the air flow meter is broken, the engine will display abnormality, and often such situations will occur: unstable idle speed, poor acceleration, intake pipe? Tempering? And black smoke from the exhaust pipe. At the same time, it causes excessive exhaust emissions.

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.

Possible phenomena are:

1, unstable idle speed

2. Increased fuel consumption

3. Weak acceleration

4. The tail gas emission is seriously polluted.

There are many kinds of air flow meters, and the damage is not the same. For example, the throttle device causes less damage to the primary meter, more damage to the secondary meter, and the primary meter may be worn and mechanically damaged. So is the flow meter in Pakistan. Vortex flowmeter may wear sensor (temperature) due to unclean medium, and rotor flowmeter may leak and wear. Ultrasonic probe damage, glass shell damage (pressure, external force) and so on.
