Transmission Temperature Sensor/Switch: Testing and Inspection

A high transaxle fluid temperature may cause the vehicle to operate in Hot Mode. While in Hot Mode, shift points may be altered, 4th gear disabled, and Torque Converter Clutch (TCC) forced ON in 2nd gear.

A failure in the TFT sensor or associated wiring should cause DTC P0712 or P0713 to set. In this case, engine coolant temperature will be substituted for the TFT sensor value, and the Transaxle will operate normally.
