Air Flow Meter/Sensor: Description and Operation
Mass Air Flow (MAF) Sensor/Intake Air Temperature (IAT) Sensor 1
The mass airflow (MAF) sensor/intake air temperature (IAT) sensor contains a hot wire and a thermistor. It is located in the intake air passage. The
resistance of the hot wire and thermistor change due to intake air flow and air temperature. The control circuit in the MAF sensor controls the current to
keep the hot wire at a set temperature. The current is converted to voltage in the control circuit, then output to the PCM.
