Hyundai Tucson: Intake Air Temperature Sensor (IATS)
Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Engine Control - Fuel System / Intake Air Temperature Sensor (IATS)
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) and its resistance is in inverse proportion to the temperature.
Specification

Harness Connector
Inspection
- Turn ignition switch OFF.
- Disconnect IATS connector.
- Measure resistance between IATS terminals 1 and 2.
- Check that the resistance is within the specification.
Specification : Refer to "Specification"
Removal
- Turn ignition switch OFF and disconnect the battery negative (-) terminal.
- Disconnect the manifold absolute pressure sensor connector (A).
- Remove the manifold absolute pressure sensor (B) after loosening the bolt.
Tightening Torque : 9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
Installation
WARNING
- Install the component with the specified torques.
- Note that internal damage may occur when the component is dropped. In this case, use it after inspecting.
- Insert the sensor in the installation hole and be careful not to damage when installation.
- Install in the reverse order of removal.

Crankshaft Position Sensor (CKPS)
Description
Crankshaft Position Sensor (CKPS) detects the crankshaft position and is one
of the most important
sensors of the engine control system. If there is no CKPS signal input, fuel is
not supplied.That is,
vehicle can't run without
Camshaft Position Sensor (CMPS)
Description
Camshaft Position Sensor (CMPS) is a hall sensor and detects the camshaft
position by using a hall
element.
It is related with Crankshaft Position Sensor (CKPS) and detects the piston
position of each cylinder
which the CKPS can

Filter replacement
The air cleaner filter can be cleaned for
inspection using compressed air. Do not
attempt to wash or to rinse it, as water
will damage the filter. If soiled, the air
cleaner filter must be replaced.
Pull up the air
Condensor - Replacement
Remove the condensor.
(Refer to Air conditioning System - "Condensor")
Using a Lwrench, remove the cap (A) on the bottom of the receiver-drier.
Remove the receiver-drier (A) from condenser using a long nose plier.
