Hyundai Palisade: Engine Control System / Intake Air Temperature Sensor (IATS)
Description and operation
Mounted inside the Manifold Absolute Pressure Sensor, Intake Air Temperature
Sensor (IATS) detects the intake air temperature.
To precisely calculate the amount of air, correction of the air temperature
is required as the air density varies with the temperature. So the ECM uses
not only MAPS signal but also IATS signal. This sensor has a Negative Temperature
Coefficient (NTC) thermistor with resistance in reverse proportion to the temperature.

Note that internal damage may occur if the component is dropped.
In this case, inspect the component before installation.
|
| • |
Insert the sensor in the installation hole and be careful not
to damage it during installation.

Description and operation
Description
The Electronic Throttle Control (ETC) System consists of a throttle body with
an integrated control motor and throttle position sensor (TPS)...
Description and operation
Description
Manifold Absolute Pressure Sensor (MAPS) is a speed-density type sensor installed
on the surge tank...
Other information:
If your temperature gage indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be overheating.
If this happens, you should:
1. Pull off the road and stop as soon
as it is safe to do so.
2. Put the vehicle in P (Park) and set
the parking brake...
After a frontal or side air bag inflates,
it will deflate very quickly. Air bag
inflation will not prevent the driver
from seeing out of the windshield or
being able to steer. Curtain air bags
may remain partially inflated for
some time after they deploy...
Categories
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger's seat.
An inflating air bag can forcefully
strike a child or child restraint resulting
in serious or fatal injury.
