Coolant Temperature Sensor/Switch (For Computer): Description and Operation
COMPONENT DESCRIPTION
The engine coolant temperature sensor is located near the No. 2 injector. The sensor is used to detect the engine coolant temperature. 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.
