Engine Coolant Temperature Switch (A/C): 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.
