It is believed that many drivers do not know what the air flow meter on the car is, and do not know how to judge whether the air flow meter of the car is normal. So how to judge when there is a problem with the car air flow meter.
In fact, the main function of the car air flow meter is to detect the size of the intake air of the engine. And convert the information of the intake air amount into an electrical signal and input it to the electronic control unit and the computer to further determine the fuel injection amount.
So what are the symptoms when the car air flow meter is broken? In fact, it will cause the car to shake at idling speed, further increase the fuel consumption, the problem of powerlessness at high speed, and the problem of black smoke from the exhaust pipe.
Usually the main reason for the damage to the air flow meter of the car is related to the inferior air filter, or the air filter is not replaced regularly. This will cause the dust in the air to stay on the hot wire of the air flow meter for a long time, and over time, it will cause a series of abnormal changes in its resistance value, which will gradually fail. And the dust will block the valve part, making it difficult for the gas to enter and exit effectively.
In the face of the above problems, the best way is to repair and replace or clean the air flow meter in time. Finally, I would like to suggest to the majority of drivers and friends that the air flow meter must be cleaned regularly in life to avoid long-term dust accumulation, which will slowly damage the car air flow meter, cause it to be damaged, and affect the normal driving of the car.
