Cooling Fan Engine Coolant Temperature (ECTF) Sensor

ECTF signals coolant temperature to PCM. On 2.0L A/T, sensor is threaded into a housing on right side of engine. On 2.5L, sensor is threaded into a coolant elbow on left side of engine. On all models, when coolant reaches a predetermined temperature, PCM sends an output signal to energize cooling fans.
