Test Description

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 5:  This step tests for an intermittent short or open condition in the engine wiring harness. The test light is used as a resistor in the circuit.
  2. 6:  This step determines if the TCM or the TFT sensor is causing a steady, unchanging TFT reading.
DTC P0711 (2.4L Hybrid)

Step Action Value(s) Yes No
1 Did you perform the Diagnostic System Check - Vehicle? - Go to Step 2  Go to Diagnostic System Check - Vehicle
2 Did you perform the Transmission Fluid Checking Procedure? - Go to Step 3  Go to Transmission Fluid Checking

  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
    3. IMPORTANT: Before clearing the DTC, use the scan tool in order to record the Failure Records. Using the Clear Info function erases the Failure Records from the TCM.
  3. Record the DTC Failure Records.
  4. Clear the DTC.
  5. Select Trans. Fluid Temp. on the scan tool.
  6. Drive the vehicle and observe the scan tool for either of the following fail conditions:
    • The TFT does not change by greater than 2°C (4°F) in 1 minute and 20 seconds when the TFT is -39°C to 20°C (-38°F to +68°F) at start-up.
    • The TFT does not change by greater than 2°C (4°F) in 1 minute and 20 seconds when the TFT is 129-149°C (264-300°F) at start-up.
Did either of the fail conditions occur?		 - Go to Step 4  Go to Testing for Intermittent Conditions and Poor Connections
4 Did the scan tool display a condition in which the TFT does not change by greater than the specified value in 1 minute and 20 seconds since startup? 2°C (4°F) Go to Step 6  Go to Step 5

  1. Turn OFF the ignition.
  2. Disconnect the AT inline 20-way connector. Additional DTCs may set.
  3. Install the J 44152  jumper harness (20 pins) on the engine side of the AT inline 20-way connector. See Special Tools .
  4. Using the J 35616  GM-approved terminal test kit, connect a test light between the TFT sensor signal circuit and the low reference circuit of the J 44152  . See Special Tools .

    Refer to Automatic Transmission Inline 20-Way Connector End View .

  5. Turn ON the ignition, with the engine OFF.
  6. While observing the scan tool display, move or wiggle the engine wiring harness from the TCM connector to the AT inline 20-way connector.
Does the TFT change by greater than the specified value?		 20°C (36°F) Go to Step 7  Go to Step 8 
6 
  1. Turn OFF the ignition.
  2. Disconnect the AT inline 20-way connector.
  3. Turn ON the ignition, with the engine OFF.
Did the scan tool display a condition in which the TFT does not change by greater than the specified value in 1 minute and 20 seconds since startup?		 2°C (4°F) Go to Step 11  Go to Step 10

  1. Test the signal circuit of the TFT sensor for an intermittent open or short condition between the TCM connector and the AT inline 20-way connector.
  2. Test the low reference circuit of the TFT sensor for an intermittent open or short condition between the TCM connector and the AT inline 20-way connector.
Refer to Circuit Testing and Wiring Repairs .Did you find and correct a condition?		 - Go to Step 12  Go to Step 11 
8
  1. Test the signal circuit of the TFT sensor for an intermittent open or short condition between the AT inline 20-way connector and the TFP manual valve position switch.
  2. Test the low reference circuit of the TFT sensor for an intermittent open or short condition between the AT inline 20-way connector and the TFP manual valve position switch.
Refer to Circuit Testing and Wiring Repairs .Did you find a condition?		 - Go to Step 9  Go to Step 10 
9 Replace the automatic transmission wiring harness.
Refer to Wiring Harness Replacement .
Did you complete the replacement?		 - Go to Step 12  -
10 Replace the TFT sensor. The TFT sensor is part of the TFP manual valve position switch.
Refer to Transmission Fluid Pressure Manual Valve Position Switch Replacement .
Did you complete the replacement?		 - Go to Step 12  -
11 Replace the TCM.
Refer to Control Module References for replacement, setup, and programming.
Did you complete the replacement?		 - Go to Step 12  -
12 Perform the following procedure in order to verify the repair:
  1. Select DTC.
  2. Select Clear Info.
  3. Drive the vehicle and ensure the TFT is greater than 20°C (68°F) and changes by greater than 2.5°C (4.5°F) for 5 seconds since startup.
  4. Select Specific DTC.
  5. Enter DTC P0711.

Has the test run and passed?		 - Go to Step 13  Go to Step 2 
13 With the scan tool, observe the stored information, capture info and DTC info.
Does the scan tool display any DTCs that you have not diagnosed?		 - Go to Diagnostic Trouble Code (DTC) List - Vehicle System OK
