DTC P0713: CVT Fluid Temperature Sensor (Open)

NOTE: 

• Before you troubleshoot, review the General Troubleshooting Information - Refer to: HOW TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS or How to Troubleshoot the CVT System(CVT) .
• This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

DTC (CVT)

1. Problem verification:

   - 1. Turn the vehicle to the ON mode.

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

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   CVTF 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 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.

2. Determine possible failure area (TATF line, others):

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

   - 2. Disconnect the following connector.

   - 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

   - 4. Turn the vehicle to the ON mode.

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

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   CVTF 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.

3. Transmission fluid temperature sensor check:

   - 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

   - 4. Turn the vehicle to the ON mode.

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

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

   Do the current condition(s) match the threshold?

   YES 

   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):

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

   - 2. Jump the SCS line with the HDS.

   SCS Short

   - 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.
