Sensor (IATS). Description and Operation
Description
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.
