Description and operation
Located in the engine coolant passage of the cylinder head, Engine Coolant Temperature
Sensor (ECTS) detects the engine coolant temperature. The ECTS uses a thermistor
that changes resistance with the temperature.
The electrical resistance of the ECTS decreases as the temperature increases,
and increases as the temperature decreases. The reference +5V is supplied to the
ECTS via a resistor in the ECM. That is, the resistor in the ECM and the thermistor
in the ECTS are connected in series. When the resistance value of the thermistor
in the ECTS changes according to the engine coolant temperature, the output voltage
also changes.
During cold engine operation, the ECM increases the frequency of fuel injection
and controls the ignition timing using the information of engine coolant temperature
to avoid engine stalling and improve drivability.

Repair procedures
| 1. |
Switch "OFF" the ignition.
|
| 2. |
Remove the ECTS (Refer to "Removal").
|
| 3. |
After immersing the thermistor of the sensor into engine coolant, measure
resistance between the ECTS terminals 3 and 4.
|
| 4. |
Check that the resistance is within the specification.

| 1. |
Switch "OFF" the ignition and disconnect the negative (-) battery terminal.
|
| 2. |
Remove the engine cover.
(Refer to Engine Mechanical System - "Engine Cover")
|
| 3. |
Remove the cowl top cover assembly.
(Refer to Body (Interior and Exterior) - Cowl Top Cover")
|
| 4. |
Disconnect the engine coolant temperature sensor connector (A).
|
| 5. |
Remove the engine coolant temperature sensor (B) from the water temperature
control assembly.
|
| • |
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.
|
| • |
Apply the engine coolant to the O-ring.
|
| • |
Insert the sensor in the installation hole and be careful not
to damage it.
|
|
| 1. |
Install in the reverse order of removal.
|
| 2. |
Replenish the engine coolant.

Kia Stinger (CK) 2018-2023 Service Manual: Condition and operation in the front passenger occupant detection system
*1 The system judges a person of adult size as an adult. When a smaller adult
sits in the front passenger seat, the system may recognize him/her as a child depending
on his/her physique and posture.
*2 Do not allow children to ride in the front passenger seat. When a larger child
who has outgrown a child restraint system sits in the front passenger seat, the
system may recognize him/her as an adult depending upon his/her physique or sitting
position.
