Chevrolet Aveo 1.3D 2012 Lt (MAF) Mass Air Flow Sensor Cleaning

The main reason that hot-film and hot-wire type sensors require cleaning is due to oils, dust, and other particles that collect onto the films or wires; adjusting their resistivity. To analyze mass air flow, one wire (or surface) is utilized as a reference, and the other is left vulnerable to the incident air flow.
