Test Description

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The number below refers to the step number on the diagnostic table.

  1. 4:  A short to voltage condition will open the TFT senor.
  1. 5:  This step tests the internal transmission wiring harness assembly for a short to voltage.
DTC P0713

Step Action Values Yes No
1 Did you perform the Diagnostic System Check - Engine Controls? - Go to Step 2  Go to DIAGNOSTIC SYSTEM CHECK -- ENGINE CONTROLS
2
  1. Install a scan tool.
  2. Turn the ignition ON, with the engine OFF.
  3. IMPORTANT: Before clearing the DTC, use the scan tool in order to record the Freeze Frame and Failure Records. Using the Clear Eng./Trans. DTC Info function erases the Freeze Frame and Failure Records from the TCM.
  4. Record the DTC Failure Records.
  5. Clear the DTC.
  6. Observe Trans. Fluid Temp. on the scan tool.
Does the scan tool display a Trans. Fluid Temp. less than or equal to the specified value?
-40°C (-40°F) Go to Step 3  Go to INTERMITTENTS

  1. Turn the ignition OFF.
  2. Disconnect the AT inline 14-way connector.
  3. Using the DMM and J-35616  GM terminal test kit, measure the resistance between the transmission fluid temperature (TFT) signal circuit (CKT 585) and the TFT sensor low reference circuit (CKT 586) of the automatic transmission. Refer to Testing for Continuity in Wiring Systems.
Is the resistance greater than the specified value?
100 K ohm Go to Step 4  Go to Step 5 
Test the TFT signal circuit (CKT 585) and the TFT low reference circuit (CKT 586) for a short to voltage between the transmission 14-way pass-through connector and the TCM. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?
- Go to Step 8  Go to Step 8 
Test the TFT signal circuit (CKT 585) and the TFT low reference circuit (CKT 586) for continuity with any other circuit at the transmission 14-way pass-through connector. Refer to Testing for Continuity and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?
- Go to Step 10  Go to Step 6 
6 Test the TFT signal circuit (CKT 585) and the TFT low reference circuit (CKT 586) for an open or a short to voltage between the TCM connector and the transmission 14-way harness connector. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?
- Go to Step 10  Go to Step 7 
7 Inspect the transmission 14-way connector and the TCM C2 connector for poor connections. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
Did you find and correct the condition?
- Go to Step 10  Go to Step 9 
8 Replace the internal automatic transmission wiring harness assembly. Refer to Wiring Harness Removal . The TFT sensor is a part of the harness assembly.
Did you complete the replacement?
- Go to Step 10  -
9 Replace the TCM. Refer to Transmission Control Module (TCM) Replacement .
Did you complete the replacement?
- Go to Step 10  -
10 Perform the following procedure in order to verify the repair:
  1. Select DTC.
  2. Select Clear Info.
  3. Drive the vehicle and ensure the following conditions are met:
    • The Trans. Fluid Temp. parameter is between -39°C (-38°F) and +149°C (+300°F).
    • The Trans. Fluid Temp. parameter changes by more than 5°C (41°F) since start-up.
  4. Select Specific DTC.
  5. Enter DTC P0713.

Does the DTC reset?
- Go to Step 2  Go to Step 11 
11 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 DEFINITIONS System OK
