The Mass Air Flow Sensor (MAF) found in Ford Explorer is quite important in regulating the air supply to the engine so as to enable maximum performance. This piece of information is transmitted to the PCM for optimizing the fuel injector timing so that; the required air-fuel mixture for proper combustion is achieved. Ford Explorers have incorporated number of different MAF sensors such as Vane Meters (VAF) or the Hot Wire sensors. This VAF sensor, as useful as it is, can choke airflow, and its mechanics can wear out frequently. On the other hand Hot Wire sensor provides high accuracy along with flexibility and the main disadvantage is that it is always prone to contamination. There are other sensors including Hot Film and Karman vortex sensors, although these are constructed with distinctive working principles, yet serve the common function of airflow measurement. It is advised that the Mass Air Flow Sensor be routinely maintained for the Ford Explorer to function optimally.
