Coolant Temperature Sensor/Switch (For Computer): Description and Operation

Fig. 83 Water Temperature Sensor

The water temperature sensor, located in the intake manifold, uses a thermistor which changes in resistance according to the coolant temperature.
As the temperature rises the resistance of the sensor lowers. The ECU interprets the resistance value as engine temperature.
