Circuit Description
Transaxle Fluid Temperature (TFT) sensor is a negative coefficient thermistor. When transaxle fluid is cold, sensor resistance is high. As transaxle fluid warms up, sensor resistance decreases. PCM uses TFT sensor information to control Torque Converter Clutch (TCC) apply and release, line pressure and shift timing. TFT range is -40 to 304°F (-40 to 151°C). DTC P0218 will set if PCM detects a high transaxle fluid temperature for extended periods of time on TFT sensor circuit.
