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

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.

Description
The hydraulic system consists of oil, an oil filter, an oil pump, and a valve body (valves and solenoid valves).
The oil pump is powered by the engine. ATF passes through the oil filter and gets distributed along the oil channels.
The oil becomes highly pressurized as it exists in ...
