Mass Air Flow (MAF) Sensor
WARNING: This page is about a different variant/trim than selected.
The mass air flow (MAF) directly measures the mass of the air flowing into the engine. The MAF sensor output is a D.C. (analog) signal ranging from about 0.5 volt to 5.0 volts used by the PCM to calculate the injector pulse width for air/fuel ratio. For transaxle strategies, the MAF sensor is used for electronic pressure control (EPC), shift and TCC scheduling.
