Intake Air Temperature
Sensor (IATS) is included inside Manifold Absolute Pressure Sensor and
detects the intake air temperature.
To calculate precise air
quantity, correction of the air temperature is needed because air density
varies according to the temperature. So the ECM uses not only MAPS signal
but also IATS signal. This sensor has a Negative Temperature Coefficient
(NTC) Thermister and it's resistance changes in reverse proportion to the
temperature.
