The Mass Air Flow (MAF) sensor is a key component in a vehicle's engine management system. It measures the amount of air entering the engine and sends this data to the engine control unit (ECU), which adjusts the air-fuel mixture for optimal combustion. A faulty MAF sensor can lead to poor engine performance, decreased fuel efficiency, and even engine stalling. Regular maintenance and cleaning of the MAF sensor can help ensure proper engine function. 1.Functionality MAF sensors work based on the
