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 and is not serviced separately. 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
The engine speed is greater than 450 RPM.
P0711
| • | No DTCs P0711, P0716, P0717, P0722, or P0723. |
| • | DTC P0711 not passed this key ON. |
| • | The TCM temperature sensor is between -39 and +149°C (-38 and +300°F). |
P0712
DTC P0712 is not failed this ignition cycle.
P0713
| • | The transmission output shaft speed is greater than 200 RPM for greater than 200 seconds. |
| • | The torque converter clutch (TCC) slip speed is equal to or greater than 120 RPM for 200 seconds or greater. |
| • | DTC P0713 is not failed this ignition cycle. |
Conditions for Setting the DTC
P0711
Fail Case 1
| • | Vehicle speed is greater than 8 km/h (5 mph) for 300 seconds cumulative. |
| • | TCC slip speed is greater than 120 RPM for 300 seconds cumulative. |
| • | The TFT is between -40 and +21°C (-40 and +70°F). |
| • | The TFT has changed by less than 2.0°C (3.6°F) in 100 seconds. |
| • | The engine coolant temperature (ECT) is greater than 70°C (158°F). |
| • | The ECT has increased by 55°C (99°F) since startup. |
Fail Case 2
| • | Vehicle speed is greater than 8 km/h (5 mph) for 300 seconds cumulative. |
| • | TCC slip speed is greater than 120 RPM for 300 seconds cumulative. |
| • | The TFT is between 120-150°C (248-302°F). |
| • | The TFT has changes by less than 2.0°C (3.6°F) in 100 seconds. |
| • | The ECT is greater than 70°C (158°F). |
| • | The ECT has increased by 55°C (99°F) since startup. |
Fail Case 3
The TCM power up temperature changes by greater than or equal to 20°C (36°F) 14 times over 7 seconds.
P0712
The TCM power up temperature is greater than or equal to 171°C (340°F) for greater than 10 seconds.
P0713
The TFT is less than or equal to -77°C (-106°F) for greater than 25 seconds.
Action Taken When the DTC Sets
| • | DTCs P0711, P0712, and P0713 are Type C DTCs. |
| • | The TCM freezes transmission adaptive functions. |
| • | The TCM allows the vehicle to operate in transmission protection mode. |
Conditions for Clearing the DTC
DTCs P0711, P0712, and P0713 are Type C DTCs.

Circuit/System Verification
- Start the engine and operate the vehicle at 64 km/h (40 mph) while observing the TCM start up temperature sensor and the TFT sensor.
- The system is operating normally if the TCM start up temperature is within 10°C (18°F) of the TFT temperature.
Circuit/System Testing
Clear the DTC and operate the vehicle under the conditions for running and setting the DTC. Verify that the DTC does not reset.
| ⇒ | If the DTC resets, replace the control solenoid (w/body and TCM) valve assembly. |
