Transaxle Temperature Sensor

The Transaxle Fluid Temperature (TFT) sensor is a thermistor which changes value based on the temperature of the transaxle fluid. A high transaxle fluid temperature may cause the vehicle to operate in Hot mode. While in Hot mode, the shift points may be altered, the 4th gear disabled, and the TCC forced on in 2nd gear.

A failure in the TFT sensor or the associated wiring should cause DTC P0712 or DTC P0713 to set. In this case, a value based on the ECT is substituted for the TFT sensor value, and the transaxle operates normally. Refer to Transmission General Description in Transmission and Drivetrain.
