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 500 RPM for 5 seconds. |
• | The ignition voltage is between 8.6 volts and 19.0 volts. |
P0711
• | No DTCs P0716, P0717, P0722, or P0723. |
• | DTC P0711 has not passed this ignition cycle. |
• | The TCM temperature sensor is between -49 and +169°C (-56 and +336°F). |
P0712
• | The output shaft speed is 200 RPM or greater for 200 seconds or more. |
• | The TCC slip speed is 120 RPM or greater for 200 seconds or more. |
• | DTC P0712 is not failed this ignition cycle. |
P0713
DTC P0713 has not failed this ignition cycle.
Conditions for Setting the DTC
P0711 - Fail Case 1
• | Vehicle speed is 8 km/h (5 mph) or greater for 300 seconds cumulative. |
• | TCC slip speed is greater than 120 RPM for 300 seconds cumulative. |
• | The TFT is between -50 and +21°C (-58 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. |
P0711 - Fail Case 2
• | Vehicle speed is 8 km/h (5 mph) or greater for 300 seconds cumulative. |
• | TCC slip speed is greater than 120 RPM for 300 seconds cumulative. |
• | The TFT is between 129-170°C (264-338°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. |
P0711 - Fail Case 3
The TFT changes by 20°C (36°F) or greater 14 times over 7 seconds.
P0711 - Fail Case 4
The TFT changes by 20°C (36°F) or less after a predetermined time.
P0712
The TFT is less than -74°C (-101°F) for 25 seconds or more.
P0713
The TFT is 174°C (345°F) or greater for 10 seconds or more.
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. |
