Multifunction Intake Air sensor

July 8, 2014

New Mass Airflow Sensor – MAF Mass Airflow Sensors (MAF) are designed to calculate the mass of the air entering the throttle body. It does this by forcing air across a hot plate or wire and measuring the amount of current needed to maintain the hot surface at a specified temperature. In effect, the MAF works by measuring wind chill on the wire. Once the PCM knows the air temperature and it’s mass, it can more effectively calculate the proper air fuel mixture. But what about humidity, doesn’t that have … Read More
