Transmission Fluid Temperature (TFT) Sensor

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

The TFT sensor is a temperature dependent resistor that is in contact with transmission fluid in the transmission sump area.

The PCM/ TCM monitors the voltage across the TFT sensor, which changes as transmission fluid temperature varies.

The PCM/ TCM uses the TFT sensor signal as an input for its strategy for shifting and TCC operation. The PCM/ TCM also uses the TFT sensor signal for transmission fault detection and diagnostics.
