What does air intake sensor do?

The air intake sensor, often referred to as the Mass Air Flow (MAF) sensor, measures the amount of air entering the engine. This information is crucial for the engine control unit (ECU) to calculate the appropriate fuel-to-air ratio for optimal combustion. By ensuring the correct mixture, the sensor helps improve engine efficiency, performance, and emissions control. If the sensor fails, it can lead to poor engine performance and increased fuel consumption.
