Normal Operation and Fault Conditions
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The TFT sensor is located in the transmission solenoid body. The resistance value of the TFT sensor varies with temperature change. The PCM monitors the voltage drop across the TFT sensor to determine the temperature of the transmission fluid. When the ignition is turned to the RUN position, the PCM uses this initial input signal to determine whether a cold start shift schedule is necessary. The cold start shift schedule allows delayed shifts when the transmission fluid is cold. The PCM inhibits TCC operation at low transmission fluid temperatures and adjusts line pressure to temperature.
DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0710 | TFT sensor circuit fault | TFT sensor circuit shorted to ground or open. |
| P0711 | TFT sensor circuit range/performance | TFT sensor indicates a valid temperature but has not changed since start up. |
| P0712 | TFT sensor circuit low fault | TFT sensor circuit short to ground. |
| P0713 | TFT sensor circuit high fault | TFT sensor circuit open. |
| P1711 | TFT sensor out of self-test range | TFT sensor indicates too hot or too cold and must indicate a normal temperature range during KOER . |
| P1783 | TFT sensor over temperature | The TFT sensor indicates that the transmission is approaching an overheating condition. |
