Intake Air Temperature Sensor: Description and Operation
Description
Intake Air Temperature Sensor (IATS) is installed inside the Mass Air Flow Sensor (MAFS) 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 MAFS signal
but also IATS signal. This sensor has a Negative Temperature Coefficient (NTC) and its resistance is in inverse proportion to the temperature.
