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 sensor is located inside of the transmission control module (TCM) assembly which has no serviceable components. The transmission fluid temperature 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, P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0401, P042E, P0658, P0668, P0669, P06AD, P06AE, P0712, P0713, P0716, P0717, P0722, P0723, P0962, P0963, P0966, P0967, P0970, P0971, P215C, P2720, P2721, P2729, or P2730 is not set.
* Engine speed is 400-7500 RPM for 5 s.
* Ignition voltage is greater than 8 V.
* Brake torque is not active.
* Engine torque signal is valid.
* Throttle position signal is valid.
P0712 and P0713
* DTC P0716, P0717, P0722, or P0723 is not set.
* Engine speed is 400-7500 RPM for 5 s.
* Ignition voltage is greater than 8 V.
Conditions for Setting the DTC
P0711
* TCM detects a 20-50° C (36-90° F) or greater difference between the transmission fluid temperature and the TCM substrate temperature, which depends on the average of the transmission fluid temperature, TCM substrate temperature, and TCM power up temperature.
* TCM detects a 20-50° C (36-90° F) or greater difference between the transmission fluid temperature and the TCM power up temperature, which depends on the average of the transmission fluid temperature, TCM substrate temperature, and TCM power up temperature.
* Above conditions have to be met for 5 min within a 6 min period.
P0712
Transmission fluid temperature is -74°C (-101°F) or lower for 1 min.
P0713
Transmission fluid temperature is 174°C (345°F) or greater for 1 min.
Action Taken When the DTC Sets
* DTCs P0711, P0712, and P0713 are Type B DTCs.
* TCM defaults to a calculated transmission fluid temperature based on 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 transmission fluid temperature sensor's output. During a road test, the transmission fluid temperature should steadily increase to a normal operating temperature, and then stabilize.

Circuit/System Verification
1. Engine idling at the normal operating temperature.
2. Verify the scan tool Transmission Fluid Temperature parameter is between -74 and +174° C (-101 and +345° F).
• If not between -74 and +174° C (-101 and +345° F)
Replace the Q8 Control
Solenoid Valve Assembly.
• If between -74 and +174° C (-101 and +345° F)
3. Verify the scan tool Transmission Fluid Temperature parameter increases greater than 2° C (3.5° F) after operating the vehicle at 64 km/h (40 mph) for 10 min.
• If the temperature does not increase greater than 2° C (3.6° F)
Replace the Q8 Control Solenoid Valve Assembly.
• If the temperature increases greater than 2° C (3.6° F)
4. Verify the scan tool Transmission Fluid Temperature and the TCM Temperature parameters are within 20° C (36° F).
• If the temperatures are not within 20° C (36° F)
Replace
the Q8 Control Solenoid Valve Assembly.
• If the temperatures are within 20° C (36° F)
5. Operate 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.
6. Verify the DTC does not set.
• If the DTC sets
Replace the Q8 Control Solenoid Valve Assembly.
• If the DTC does not set
7. All OK.
