Engine Coolant Temperature (ECT) Sensor

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The engine coolant temperature (ECT) sensor is a 2 wire thermistor sensor which changes resistance as temperature changes. The resistance of the sensor increases as engine temperature decreases and the voltage sent to the powertrain control module (PCM) increases. The PCM uses this information to help determine TCC operation.
