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.
