Hyundai Ioniq (AE): Engine Control System / Intake Air Temperature Sensor (IATS). Description and operation

Hyundai Ioniq (AE) 2017-2022 Service & Repair Manual / Engine Control/Fuel System / Engine Control System / Intake Air Temperature 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.

    Inspection1.Check the MAFS visually.– Mounting direction correct. – Any contamination, corrosion or damage on connector.

    Specification Temperature Resistance (kΩ) °C °F -40-4040.
