What Is A Mass Air Flow Sensor?
There are two main types MAF sensors- hot wire and cold wire. A hot wire MAF sensor uses a platinum wire located in the path of air flow, which is heated using specific voltage. As the air passes over the hot wire, it is cooled, decreasing the wire’s resistance to voltage. The engine control module (ECM) measures this change and alters the tune accordingly. The other type is a cold wire sensor. These are commonly found in GM engines. These sensors use both a hot wire and a cold wire, where the cold wire functions as a reference for the hot wire.
