Coolant Temperature Sensor/Switch (For Computer): Description and Operation
Engine Coolant Temperature Sensor
DESCRIPTION
The engine coolant temperature sensor is used to detect the engine coolant temperature.
Resistance / Temperature
Voltage / Resistance
The sensor modifies a voltage signal from the ECM. The modified signal returns to the ECM as the engine coolant temperature input.
The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature
increases.
