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
* DTC 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 is not set.
* Engine speed is 400 RPM or greater for 5 seconds.
* Ignition voltage is 8.6 volts or greater.
* Brake torque is not active.
* Engine torque signal is valid.
* Throttle position signal is valid.
P0712
* DTC P0712, P0716, P0717, P0722, or P0723 is not set.
* Engine speed is 400 RPM or greater for 5 seconds.
* Ignition voltage is 8.6 volts or greater.
P0713
* DTC P0713, P0716, P0717, P0722, or P0723 is not set.
* Engine speed is 400 RPM or greater for 5 seconds.
* Ignition voltage is 8.6 volts or greater.
Conditions for Setting the DTC
P0711
Difference between the TFT and TCM temperature and the difference between the TFT and TCM power up temperature are both greater than 20-50°C (36-90°F). The temperature threshold is dependent on the average temperature of the TFT, TCM temperature, and TCM power up temperature. The conditions have to be met for 5 minutes within a 6 minute period.
P0712
TFT is -74°C (-101°F) or lower for 1 minute.
P0713
TFT is 174°C (345°F) or greater for 1 minute.
Action Taken When the DTC Sets
* DTCs P0711, P0712, and P0713 are Type B DTCs.
* TCM defaults the TFT to the TCM Temperature.
Conditions for Clearing the DTC
DTCs P0711, P0712, and P0713 are Type B DTCs.
Diagnostic Aids
The TCM temperature sensor is located inside of the control solenoid valve assembly and its output should resemble that of the TFT sensor output.

Circuit/System Verification
1. Verify the scan tool Trans. Fluid Temp. parameter is between -74 and +174°C (-101 and +345°F) with the engine idling at operating temperature.
• If not within the specified range
Replace the Q8 control solenoid valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly Replacement Service and Repair.
• If within the specified range
2. Operate the vehicle at 64 km/h (40 mph) for 10 minutes. Verify the scan tool TCM Temperature and Trans. Fluid Temp. parameters are within 20°C (36°F) of each other and DTC P0711, P0712, or P0713 is not set.
• If parameters are not within 20°C (36°F) or DTC P0711, P0712 P0713 set
Replace the Q8 control solenoid valve assembly.
• If parameters are within 20°C (36°F) and DTC P0711, P0712 P0713 did not set.
3. After performing the above steps, verify that the DTC does not reset by operating the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data. If the vehicle passes the Circuit/System Verification procedure, refer to Testing for Intermittent Conditions and Poor Connections Testing for Intermittent Conditions and Poor Connections.
