The Mass Air Flow (MAF) sensor is a critical component in your vehicle's engine management system. It measures the amount of air entering the engine, providing vital data to the engine control unit (ECU). This data allows the ECU to precisely calculate the correct amount of fuel to inject for optimal combustion. A properly functioning MAF sensor contributes to smooth engine operation, improved fuel economy, and reduced emissions. If you notice symptoms such as rough idling, poor acceleration, decreased fuel mileage, or a check engine light, your MAF sensor may need inspection or replacement. This MEAT & DORIA sensor is designed to meet or exceed original equipment specifications.
