Mass Air Flow (MAF) Sensor

This sensor directly measures the mass of the air flowing into the engine. The sensor output is a DC (analog) signal ranging from about 0.5 volt to 5 volts by the PCM to calculate the injector pulse width for stoichiometry. The Mass Air Flow (MAF) sensor input is used for Electronic Pressure Control (EPC), shift and TCC control.
