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.
