Accent GL Sedan L4-1495cc 1.5L SOHC MFI (1997)
Coolant Temperature Sensor/Switch (For Computer): Description and Operation
ENGINE COOLANT TEMPERATURE (ECT) SENSOR
The engine coolant temperature sensor is installed in the engine coolant passage of the cylinder head, detects engine coolant temperature and emits
signals to the ECM. This part employs a thermistor which is sensitive to changes in temperature. The electric resistance of a thermistor decreases
in response to temperature rise. The ECM judges engine coolant temperature by the sensor output voltage and provides optimum fuel enrichment
when the engine is cold.
