What to Do If the Air Flow Sensor Is Broken?

[CharlotteLynn]

If the air flow sensor is broken, you can go to a 4S shop for repair or replacement. Here is more information about the air flow sensor: 1. The air flow sensor is one of the important sensors in an electronic fuel injection engine. It converts the inhaled air flow into an electrical signal and sends it to the electronic control unit (ECU), serving as one of the basic signals for fuel injection. It is a sensor that measures the air flow inhaled by the engine. 2. If the air flow sensor or its circuit malfunctions, the ECU cannot receive the correct air intake signal, leading to improper control of fuel injection. This may result in an overly rich or lean air-fuel mixture, causing abnormal engine operation. 3. The biggest advantage of the air flow sensor is that its calibration coefficient is not affected by the properties of the measured medium, allowing it to be applied from one typical medium to others. 4. A malfunctioning air flow sensor generally does not prevent the engine from starting, but it can affect the engine's performance, such as unstable idling, poor acceleration, "backfire" in the intake pipe, and black smoke from the exhaust pipe, while also causing excessive exhaust emissions.
