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°C (36-90°F). The temperature threshold is dependent on the average temperature of the TFT, TCM temperature, and TCM power up temperature.

P0712

The TFT is less than -74°C (-101°F) for 1 minute.

P0713

The 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.
* The 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 transmission control module (TCM) temperature sensor is located inside of the control solenoid valve assembly and its output should resemble that of the transmission fluid temperature (TFT) sensor's output.

Circuit/System Verification

1. Engine idling at operating temperature, verify the scan tool Trans Fluid Temp. parameter is between -74 and +174°C (-101 and +345°F).

• If not within the specified range, replace the control solenoid valve assembly.

2. Operate the vehicle at 64 km/h (40 mph) for 10 minutes. Monitor the TCM Temperature, TCM Power up Temperature, and the Trans. Fluid Temp. parameters with a scan tool. The TCM Temperature and the Trans. Fluid Temp. parameters should be within 25°C (45°F) of each other, and the Trans. Fluid Temp. and TCM Power up Temperature parameters should be within 25°C (45°F) of each other.

• If both are greater than the specified range, replace the control solenoid valve assembly.

3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

Repair Instructions

Note:
* Perform the Reset Transmission Adapts Programming and Relearning following all transmission related repairs.
* Before replacing the TCM, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection Component Tests and General Diagnostics.

Perform the Diagnostic Repair Verification Verification Tests after completing the diagnostic procedure.
