A Mass Air Flow (MAF) sensor is a critical component in a vehicle's fuel injection system, responsible for measuring the amount of air entering the engine. This information is sent to the engine control unit (ECU), which uses it to determine the correct amount of fuel to inject for optimal combustion. By providing precise air flow data, the MAF sensor helps ensure efficient engine performance, better fuel economy, and reduced emissions. A properly functioning MAF sensor is essential for maintaining the engine's air-fuel ratio, preventing issues such as rough idling, poor acceleration, and increased fuel consumption.
