NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information See HOW TO TROUBLESHOOT THE A/T SYSTEM or HOW TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS .
This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

DTC Description	Confirmed DTC	Pending DTC	Freeze Frame
P0713 ATF Temperature Sensor (Open)

Problem verification:

1. Turn the ignition switch to ON (II).

2. Check the parameter(s) below with the HDS.

Signal	Threshold		Current conditions
Signal	Values	Unit	Values	Unit
ATF Temp Sensor (V)	More than 4.93	V

Do the current condition(s) match the threshold?

YES : The failure is duplicated. Go to step 2.

NO : Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between the ATF temperature sensor and the PCM.

Determine possible failure area (TATF line, others):

1. Turn the ignition switch to LOCK (0).
2. Disconnect the following connector.
Shift solenoid wire harness 8P connector
3. Connect terminals A and B with a jumper wire.
Terminal A Shift solenoid wire harness 8P connector No. 7 (RED)

Terminal B Body ground

4. Turn the ignition switch to ON (II).

5. Check the parameter(s) below with the HDS.

Signal	Threshold		Current conditions
Signal	Values	Unit	Values	Unit
ATF Temp Sensor (V)	Less than 0.07	V

Do the current condition(s) match the threshold?

YES : Go to step 3.

NO : Go to step 4.

ATF temperature sensor check:

1. Turn the ignition switch to LOCK (0).
2. Remove the jumper wire.
3. Connect terminals A and B with a jumper wire.
Terminal A Shift solenoid wire harness 8P connector No. 6 (GRY)

Terminal B Shift solenoid wire harness 8P connector No. 7 (RED)

4. Turn the ignition switch to ON (II).

5. Check the parameter(s) below with the HDS.

Signal	Threshold		Current conditions
Signal	Values	Unit	Values	Unit
ATF Temp Sensor (V)	Less than 0.07	V

Does the ATF Temp Sensor (V) remain 0.07 V or below?

YES : Replace the ATF temperature sensor See ATF TEMPERATURE SENSOR REMOVAL AND INSTALLATION , then do the repair verification .

NO : The ATF temperature sensor is OK. Repair an open in the SG2 wire between the shift solenoid wire harness and the PCM, then do the repair verification .

Open wire check (TATF line):
- 1. Turn the ignition switch to LOCK (0).
- 2. Remove the jumper wire.
- 3. Jump the SCS line with the HDS.
- 4. Disconnect the following connector.
  PCM connector B (49P)
- 5. Check for continuity between test points 1 and 2.
  Test condition IG LOCK (0)
  
  Shift solenoid wire harness 8P connector: disconnected
  
  PCM connector B (49P): disconnected
  
  Test circuit TATF
  
  Test point 1 Shift solenoid wire harness 8P connector No. 7 (RED)
  
  Test point 2 PCM connector B (49P) No. 38 (RED)

Is there continuity?

YES : The TATF wire is OK. Update the PCM if it does not have the latest software See PCM REMOVAL AND INSTALLATION or PCM UPDATE , or substitute a known-good PCM See PCM REMOVAL AND INSTALLATION or PCM UPDATE , then do the repair verification .

NO : Repair an open in the TATF wire between the shift solenoid wire harness and the PCM, then do the repair verification .
