MAF Sensors, found within the Engine Electronics section of Engine Parts, are critical components in modern passenger cars and commercial vehicles. These Mass Air Flow sensors accurately measure the volume of air entering the engine, providing data essential for the engine control unit (ECU) to calculate the correct fuel injection timing and amount. Proper MAF sensor function ensures optimal engine performance, fuel efficiency, and emissions control. Located in the intake system, typically between the air filter and the throttle body, MAF sensors utilize a hot-wire or hot-film technology to determine airflow. Examples in our assortment include Bosch MAF Sensors with part numbers 0280218116, 0280218037, and 0281002978, designed for a wide range of vehicle applications. A failing MAF sensor can cause rough idling, poor acceleration, and illuminated check engine lights.
