Coolant Temperature Sensor/Switch (For Computer): Description and Operation
PURPOSE/OPERATION
The engine coolant temperature monitors the coolant temperature and inputs it to the engine control module as a Voltage signal. As engine
temperature increases, sensor resistance decreases. The ECM monitors engine temperature by the sensor output Voltage and provides optimum
fuel enrichment when the engine is cold.
