Test Description

WARNING: This page is about a different car, the 2003 Saturn LW300, 2003 Saturn LW200, 2003 Saturn L300, and 2003 Saturn L200. 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 the TFT sensor signal circuit for being shorted to another circuit within the transmission. If the TFT sensor signal circuit shorts to another circuit, which is carrying voltage greater than five volts, the TFT sensor would become open.
  2. 6:  This step tests the TFT sensor signal circuit for being shorted to voltage, which would be the cause for the open in the TFT sensor.
DTC P0713 (2.2L (L61))

Step Action Value(s) Yes No
1 Did you perform the Diagnostic System Check - Engine Controls? - Go to Step 2  Go to DIAGNOSTIC SYSTEM CHECK - ENGINE CONTROLS in Self-Diagnostics - 3.0L or DIAGNOSTIC SYSTEM CHECK -- ENGINE CONTROLS in Self-Diagnostics - 2.2L

  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
    IMPORTANT: Before clearing the DTC, use the scan tool in order to record the DTC Failure Records. Using the Clear Info function erases the Failure Records from the PCM.
  3. Record the DTC Failure Records.
  4. Clear the DTC.
  5. Select TFT Sensor on the scan tool.
Does the scan tool display a TFT sensor voltage greater than the specified value?		 4.92 V Go to Step 3  Go to INTERMITTENTS for 2.2L or INTERMITTENT CONDITIONS for 3.0L

  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 transmission side of the AT inline 20-way connector.
  4. Using the DMM and the J-35616  connector test adapter kit, measure the resistance between terminal L and M of the J 44152 .

    Refer to AUTOMATIC TRANSMISSION INLINE 20-WAY CONNECTOR for 2.2L or AUTOMATIC TRANSMISSION INLINE 20-WAY CONNECTOR for 3.0L.

Is the resistance less than the specified value?		 100K ohm Go to Step 7  Go to Step 4 
4
  1. Test the signal circuit (CKT 1227) of the TFT sensor for an open between the AT inline 20-way connector and the TFT sensor.
  2. Test the low reference circuit (CKT 407) of the TFT sensor for an open between the AT inline 20-way connector and the TFT sensor.

    Refer to Testing for Continuity in Wiring Systems.

Did you find an open condition?		 - Go to Step 8  Go to Step 5 
5  Measure the resistance between terminal L and all other terminals of the J 44152 .
Is the resistance between terminal L and any other terminal less than the specified value?		 1,000 ohm Go to Step 10  Go to Step 6 
6  Test the signal circuit (CKT 1227) of the TFT sensor for a short to voltage between the PCM connector C1 and the AT inline 20-way connector.
Refer to Testing for a Short to Voltage and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 9  Go to Step 9 
7
  1. Test the signal circuit (CKT 1227) of the TFT sensor for an open between the PCM connector C1 and the AT inline 20-way connector.
  2. Test the low reference circuit (CKT 407) of the TFT sensor for an open between the PCM connector C2 and the AT inline 20-way connector.
Refer to Testing for Continuity and Wiring Repairs in Wiring Systems.Did you find and correct an open condition?		 - Go to Step 12  Go to Step 11 
8 Replace the automatic transmission wiring harness.
Refer to WIRING HARNESS REMOVAL and WIRING HARNESS CONNECTION .
Did you complete the replacement?		 - Go to Step 12  -
9 Replace the TFP manual valve position switch.
Refer to Transmission Fluid Pressure (TFP) Manual Valve Position Switch Replacement
Did you complete the replacement?		 - Go to Step 12  -
10
  1. Replace the automatic transmission wiring harness.

    Refer to WIRING HARNESS REMOVAL and WIRING HARNESS CONNECTION .

  2. Replace the TFP manual valve position switch.

    Refer to Transmission Fluid Pressure (TFP) Manual Valve Position Switch Replacement

Did you complete the replacements?		 - Go to Step 12  -
11 Replace the PCM.
Refer to POWERTRAIN CONTROL MODULE in Removal & Installation.
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. Operate the vehicle under the following conditions:
    • Turn ON the ignition, with the engine OFF.
    • The TFT signal voltage must be less than 4.92 volts for 6 minutes and 40 seconds.
  4. Select Specific DTC.
  5. Enter DTC P0713.

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 TESTS in Self-Diagnostics - 2.2L or DIAGNOSTIC TESTS in Self-Diagnostics - 3.0L System OK
