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

OPERATION
The ECT sensor changes resistance in response to the engine coolant temperature. Resistance decreases as the surrounding temperature increases
providing a signal to the Powertrain Control Module (PCM) that indicates the engine coolant temperature.
