Kia Cee'd: Engine Control System / Intake Air Temperature Sensor (IATS) Description and operation

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.

Manifold Absolute Pressure Sensor (MAPS) Repair procedures

Inspection 1. Connect the GDS on the Data Link Connector (DLC). 2. Measure the output voltage of the MAPS at idle and IG ON. ...
