DTC Descriptors



DTC P0711



- Transmission Fluid Temperature (TFT) Sensor Performance



DTC P0712



- Transmission Fluid Temperature (TFT) Sensor Circuit Low Voltage



DTC P0713



- Transmission Fluid Temperature (TFT) Sensor Circuit High Voltage



Circuit/System Description



The transmission fluid temperature (TFT) sensor is located inside of the transmission control module (TCM) assembly which has no serviceable



components. The TFT sensor provides transmission fluid temperature to the TCM. This fault is handled inside the TCM and no external circuits are



involved.



Conditions for Running the DTC



P0711



* No DTCs P0101, P0102, P0103, P0106, P0107, P0108, P0171, P0172, P0174, P0175, P0201, P0202, P0203, P0204, P0205, P0206, P0207,



P0208, P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, P0401, P042E, P0658, P0668, P0669, P06AD, P06AE, P0711,



P0712, P0713, P0716, P0717, P0722, P0723, P0962, P0963, P0966, P0967, P0970, P0971, P215C, P2720, P2721, P2729, or P2730.



* The engine speed is greater than 400 RPM for 5 seconds.



* The ignition voltage is 8.6 volts or greater.



* Brake torque is not active.



* The engine torque signal is valid.



* The throttle position signal is valid.



P0712



* No DTCs P0712, P0716, P0717, P0722, or P0723.



* The engine speed is greater than 400 RPM for 5 seconds.



* The ignition voltage is 8.6 volts or greater.



P0713



* No DTCs P0713, P0716, P0717, P0722, or P0723.



* The engine speed is greater than 400 RPM for 5 seconds.



* The ignition voltage is 8.6 volts or greater.



Conditions for Setting the DTC



P0711



The difference between the transmission fluid temperature (TFT) and TCM temperature and the difference between the TFT and TCM power up



temperature are both greater than 20-50掳C (36-90掳F). The temperature threshold is dependent on the average temperature of the TFT, TCM



temperature, and TCM power up temperature.
