TROUBLESHOOTING HINT
Fail-safe
- No fail-safe (KOEO, KOER disabled completing diagnostic routines)

TFT sensor description
- The TFT sensor is located on the solenoid valve body. It is a temperature-sensitive device called a thermistor. The resistance value of the TFT sensor will vary with temperature.
- The PCM monitors the voltage across the TFT sensor to determine the ATF temperature. The PCM uses this signal to determine shift schedule and to control line pressure for cold and hot temperature operation. The PCM also inhibits Torque Convener Clutch (TCC) operation at tow ATF temperature and adjusts Electronic Pressure Control (EPC) pressure for temperature.
