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 5.0 volts by the powertrain control module to calculate the injector pulse width for stoichiometry. The mass air flow (MAF) sensor input is used for EPC pressure control, shift and torque converter clutch (TCC) control.
