TFT sensor description
- The thermistor type Transaxle Fluid Temperature (TFT) sensor is used.
- The TFT sensor is located on the valve body.
- The TFT sensor detects ATF temperature according to the resistance change in the thermistor and sends signals to the PCM.
- The PCM monitors the voltage across the TFT sensor to determine the ATF temperature. The PCM uses this signal to determine shift schedule and control line pressure for cold and hot temperature operation. The PCM also inhibits Torque Converter Clutch (TCC) operation at low ATF temperature and adjusts pressure control solenoid.
- TFT sensor signal is used for following controls and monitors:
- Shift control -Line pressure control
- Timing control
- TCC control
- Engine-transaxle total control (Torque reduction control)
- Slope mode control
- OBD system
