Transmission Fluid Temperature (TFT) Sensor

Transaxle Electronic Control System

Transmission Fluid Temperature (TFT) Sensor

The Transmission Fluid Temperature (TFT) sensor is located on the internal wiring harness to the solenoid valves in the transmission fluid pan.

It is a resistor and measures the TFT.

The TFT is used by the PCM for the following functions:

- Applying the TCC is not permitted until the transmission fluid reaches a certain temperature.
- Engagement of 4th gear is prevented in extreme sub-zero temperatures until the normal operating temperature is reached.
- If the TFT is excessive, a pre-set fixed shift curve is selected and the TCC is closed in 2, 3 and 4, and the transaxle warning indicator is activated. No substitute signal is available for the TFT sensor.
