What is a Mass Air Flow (MAF) sensor? A MAF sensor monitors the temperature and weight of air entering your engine. Your onboard computer needs that information to calculate the right amount of fuel for all engine operating conditions. The sensor works by heating a delicate platinum wire or plate and measuring the current required to keep it at a constant temperature while air blows past it. Over time, …

How to Service an Automotive Engine Mass Air Flow Sensor

+

The mass air flow sensor is a device that measures the amount of air entering the engine and supplies this information to the engine control unit (ECU). The ECU uses this information to calculate engine load, which the ECU uses along with information provided by the oxygen sensor(s) to precisely control the engine’s air / fuel ratio. Engine load measurement is also …
