A Mass Air Flow (MAF) sensor monitors the temperature and weight of air entering your engine. Your onboard computer needs that information to calculate the right amount of petrol 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, dust and oil particles stick to the hot wire/plate and bake on. Eventually, those baked-on particles insulate the wire/plate from the airstream. This causes starting, idling and acceleration problems, as well as poor gas mileage
