Kia Sorento: Engine Coolant temperature sensor (ECTS) Description and Operation
Kia Sorento (MQ4, 2021-2026) Service Manual / Engine Control / Fuel System / Engine Control System / Engine Coolant temperature sensor (ECTS) Description and Operation
| Description |
| • |
The Engine Coolant Temperature Sensor (ECTS) uses a thermistor whose resistance changes 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 Engine Control Module (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 fuel injection duration and controls the ignition
timing using the information of engine coolant temperature to avoid engine stalling and improve drivability.
