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 SystemsHow to Troubleshoot the CVT System(CVT System) .
• This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

• 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 an intermittent short to ground in the TATF wire 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 A 8P connector No. 7
  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 A 8P connector No. 6
  Terminal B	Solenoid wire harness A 8P connector No. 7

  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 solenoid wire harness A - Refer to: Solenoid Wire Harness B Removal and InstallationSolenoid Wire Harness A Removal and Installation .

  NO 

  The transmission fluid temperature sensor is OK. Repair an open in the SG2 wire between the solenoid wire harness A 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, and wait more than 1 minute.

  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 A 8P connector: disconnected
  	PCM connector C (51P): disconnected
  Test point 1	Solenoid wire harness A 8P connector No. 7
  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 A and the PCM.
