Hyundai Genesis: Engine Control System / Intake Air Temperature Sensor (IATS) Description and Operation

Hyundai Genesis (DH) 2013-2016 Service 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 Barometric Pressure Sensor and detects the intake air temperature.

To calculate exact air quantity, correction of the air temperature is needed because air density varies according to the temperature. So the ECM uses not only BPS signal but also IATS signal. This sensor has a Negative Temperature Coefficient (NTC) thermistor and its resistance changes in reverse proportion to the temperature.

Barometric Pressure Sensor (BPS) Repair procedures

Inspection 1. Connect the GDS on the Data Link Connector (DLC). 2. Measure the output voltage of the BPS at idle and with the ignition ON. Specification: Refer to "Specification" Remo ...
