What is the normal data for the Toyota Reiz air flow meter?

[VanCalvin]

Under normal circumstances, the data stream of the air flow meter is around 2.5g/s. If it is below 2.0g/s, it indicates an air leak in the intake system, while a reading above 4.0g/s suggests there is some pressure in the intake system, meaning an additional load. Here is more detailed information: 1. Damaged air flow meter: When the air flow meter is damaged, it often results in unstable idling, weak acceleration when overtaking, black smoke emission, and in severe cases, the vehicle may fail to start. If you suspect an issue with the air flow meter, you can unplug its connector and then try to start the vehicle. If it starts, it confirms the problem is with the air flow meter. 2. Common types of air flow meters: Common air flow meters include vane-type, optical-type, Karman vortex-type, ultrasonic-type, hot-wire-type, and hot-film-type. Their main function is to detect the engine's intake air volume or intake air temperature, and some also have the capability to measure external atmospheric pressure. The intake air volume is converted into an electrical signal and sent to the ECM, which then controls the fuel injection volume to achieve optimal combustion efficiency.
