TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR FUNCTION
CHU051319010S01
•
The TFT sensor detects the ATF temperature in the oil pan, and sends control signals to the TCM. The TCM
controls the driving pattern selection and the torque converter clutch based on signals from the TFT sensor.

TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR CONSTRUCTION/OPERATION
CHU051319010S02
•
The TFT sensor is a thermistor type and the resistance changes according to the ATF temperature.
•
The characteristic of the resistance is as shown in the figure below: when the ATF temperature increases, the
resistance decreases, and when the ATF temperature decreases, the resistance increases.
•
The TFT sensor is integrated with the wiring harness component.

TURBINE SENSOR FUNCTION
CHU051319010S03
•
The turbine sensor is located in the transmission case with clearance between it and the reverse and high
