2024 Kia Forte LXFACTORY OEM SERVICE PROCEDURE
Description And Operation: Description
- Engine Coolant Temperature Sensor (ECTS) detects the engine coolant temperature.
- The thermistor of ECTS has a characteristic of Negative Temperature Coefficient (NTC), which means temperature and resistance are inversely proportional to each other.
- The reference +5 V 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.
- To prevent the engine stop or hesitation during the cold start, the ECM calibrates the fuel injection amount and the injection timing based on the engine coolant temperature information.
