Intake Air Temperature Sensor: Description and Operation
Mass Air Flow (MAF) Sensor/Intake Air Temperature (IAT) Sensor
The mass air flow (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 changes due to intake air temperature and air flow. 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.
