Century V6-3100 3.1L VIN M SFI (1998)
Transmission Temperature Sensor/Switch: Testing and Inspection
OPERATION
The Transaxle fluid temperature sensor is a thermistor which changes value based on the temperature of the Transaxle fluid.
DIAGNOSIS
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 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. For DTC diagnosis refer to System Diagnosis /
Diagnostic Tables / Diagnostic Trouble Code Tables. See: Powertrain Management/Computers and Control Systems/Testing and Inspection
Refer to Automatic Transaxle Diagnosis for a complete description of the TFT sensor.
