Description and operation
Description

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.

Removal
1.

Switch "OFF" the ignition and disconnect the negative (-) battery terminal.

2.

Remove the engine cover.

(Refer to Engine Mechanical System - "Engine Cover")

3.

Disconnect the intake air temperature sensor connector (A).

4.

Remove the installation bolts (B), and then remove the sensor from the intake manifold.

9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)

Installation
  
•

Install the component to the specified torques.

•

Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.

•

Insert the sensor in the installation hole and be careful not to damage it.

1.

Install in the reverse order of removal.

Kia Stinger (CK) 2018-2023 Service Manual: Windshield wipers

Operates as follows when the ignition switch is turned ON. MIST : For a single wiping cycle, move the lever to this (MIST) position and release it. The wipers will operate continuously if the lever is held in this position. OFF : Wiper is not in operation INT : Wiper operates intermittently at the same wiping intervals. Use this mode in light rain or mist.

Kia Stinger (CK) 2018-2023 Service Manual: Immobilizer system

Your vehicle is equipped with an electronic engine immobilizer system to reduce the risk of unauthorized vehicle use. Whenever the ENGINE START/STOP button is changed to the ON position, the immobilizer system checks and verifies if the key is valid or not. If the key is valid, the engine will start. If the key is invalid, the engine will not start.
