Circuit/System Description

The transmission fluid temperature (TFT) sensor is located inside of the transmission control solenoid valve assembly which has no serviceable components. The TFT sensor provides transmission fluid temperature to the transmission control module (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, P0717, P0722, P0723, P0962, P0963, P0966, P0967, P0970, P0971, P215C, P2720, P2721, P2729, or P2730 is not set.
    • The engine speed is greater than 400 RPM for 5 seconds.
    • The ignition voltage is greater than 9.0 volts.
    • The throttle position signal is valid.
    • The engine torque signal is valid.

P0712

    • The engine speed is greater than 400 RPM for 5 seconds.
    • The ignition voltage is greater than 9.0 volts.
    • DTC P0712, P0716, P0717, P0722, or P0723 is not set.

P0713

    • The engine speed is greater than 500 RPM for 5 seconds.
    • The ignition voltage is greater than 9.0 volts.
    • DTC  P0713, P0716, P0717, P0722, or P0723 is not set.

Conditions for Setting the DTC

P0711

The 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) for 4 seconds. The temperature threshold is dependent on the average temperature of the TFT, TCM temperature, and TCM power up temperature.

P0712

The TFT is greater than 254°C (489°F) for 1 minute.

P0713

The TFT is less than -254°C (-425°F) for 1 minute.

Action Taken When the DTC Sets

    • DTCs P0711, P0712, and P0713 are Type B DTCs.
    • The TCM defaults to a calculated TFT based on the TCM temperature.

Conditions for Clearing the DTC

DTCs P0711, P0712, and P0713 are Type B DTCs.

Diagnostics Aids

The TCM temperature sensor is located inside of the control solenoid valve assembly and its output should resemble that of the TFT sensor's output.

Circuit/System Verification

  1. Engine ticking over at operating temperature, verify the scan tool Trans Fluid Temp. parameter is between -254 and +254°C (-425 and +489°F).
  2. If not within the specified range, replace the Q8 control solenoid valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly Replacement .
  3. Operate the vehicle at 64 km/h (40 mph) for 10 minutes. Monitor the Transmission Fluid Temperature parameter and the TCM Temperature parameter with a scan tool. The Transmission Fluid Temperature parameter should increase by greater than 2°C (3.5°F). Also, the Transmission Fluid Temperature parameter and the TCM Temperature parameter should be within 20°C (36°F) of each other.
  4. If the Transmission Fluid Temperature parameter does not increase by greater than 2°C (3.5°F) or the Transmission Fluid Temperature parameter is not within 20°C (36°F) of the TCM Temperature parameter, then replace the Q8 control solenoid valve assembly.
  5. 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 then, refer to Testing for Intermittent Conditions and Poor Connections .

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

       Note: Before replacing the TCM, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection .

    • Refer to Control Module References for control solenoid valve assembly replacement, set-up, and programming.
    • Perform the Transmission Adaptive Values Learn following all transmission related repairs.
