MAF Sensor/IAT Sensor
The MAF sensor/IAT sensor is located in the intake air passage and contains a hot wire sensor, a cold wire sensor and a thermistor. The resistance of the hot wire sensor, the cold wire sensor, and the 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 outputted to the PCM.
