In some applications, the PCM translates the base data input into a grams-per-second (GPS) data line indicating the metric weight of the air flowing into the engine. This variation in current flow, which is a base data input, is then translated into a voltage or frequency signal that is sent as a secondary data input to the PCM. The amperage flow through the resistor changes because the electrical resistance of the resistor is responding to the cooling effects of rapidly moving air. In general, a “hot wire” MAF sensor produces an input to the PCM when a low-amperage electrical current is passed through a metal-film resistor suspended in the MAF’s air stream.
