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.
