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 and loose terminals between the transmission fluid temperature sensor and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.?

Determine possible failure area (TATF line, others):

Determine possible failure area (TATF line, others)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Disconnect the following connector.
Solenoid wire harness 8P connector (engine wire harness side)


?3.
Connect terminals A and B with a jumper wire.
Terminal A
Solenoid wire harness 8P connector (engine wire harness side) No. 3
Terminal B
Body ground

?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Remove the jumper wire.

?3.
Connect terminals A and B with a jumper wire.
Terminal A
Solenoid wire harness 8P connector (engine wire harness side) No. 2
Terminal B
Solenoid wire harness 8P connector (engine wire harness side) No. 3

Faulty transmission fluid temperature sensor. Replace the solenoid wire harness.?
     
NO
     
     
     
The transmission fluid temperature sensor is OK. Repair an open in the SG2 wire between the solenoid wire harness and the PCM.?
4.
Open wire check (TATF line):

Open wire check (TATF line)
?1.
Turn the vehicle to the OFF (LOCK) mode.

?2.
Jump the SCS line with the HDS.


?3.
Disconnect the following connector.
PCM connector C (51P)

?4.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
 
Solenoid wire harness 8P connector (engine wire harness side): disconnected
 
PCM connector C (51P): disconnected
Test point 1
Solenoid wire harness 8P connector (engine wire harness side) No. 3
Test point 2
PCM connector C (51P) No. 37


Is there continuity?

     
YES
     
     
     
The TATF wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P0713 goes away and the PCM was updated, troubleshooting is complete. If DTC P0713 goes away and the PCM was substituted, replace the original PCM.?
     
NO
     
     
     
Repair an open in the TATF wire between the solenoid wire harness and the PCM.?
