Transmission Temperature Sensor/Switch: Description and Operation
General Description
The transmission fluid temperature sensor is a thermistor which changes its resistance based on the temperature of the transmission fluid. For a
complete description of the
TFT sensor, refer to 4L30-E Automatic Transmission Diagnosis.
A failure in the TFT sensor or associated wiring will cause DTC P0712 or DTC P0713 to set. In this case, engine coolant temperature will be
substituted for the TFT sensor value and the transmission will operate normally.
