DTC Troubleshooting: P0713 (28-4)

DTC P0713:

Open in ATF Temperature Sensor Circuit

• Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information.
• This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1.	Check the ATF temperature sensor voltage with the HDS in the A/T data list. Does the ATF temperature sensor voltage exceed 4.93 V? YES - Go to 2. NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ATF temperature sensor and the PCM.n

2.	Turn the ignition switch OFF.

3.	Disconnect the shift solenoid harness connector at the shift solenoid valve cover.

4.	Turn the ignition switch ON (II).

5.	Measure voltage between solenoid harness connector terminal No. 6 and body ground.   Is there about 5 V? YES - Go to 6. NO - Go to 7.

6.

Measure voltage between shift solenoid harness connector terminals No. 6 and No. 7.   Is there about 5 V? YES - Replace the ATF temperature sensor-shift solenoid harness connector, then go to 11. NO - Repair open in the wire between PCM connector terminal B33 and the shift solenoid harness connector, then go to 11.

7.	Turn the ignition switch OFF.

8.	Jump the SCS line with the HDS.

9.	Disconnect PCM connector B (44P).

10.

Check for continuity between PCM connector terminal B27 and shift solenoid harness connector terminal No. 6.   Is there continuity? YES - Check for loose or poor connections at PCM connector terminal B27. If the connection is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original  PCM.n NO - Repair open in the wire between PCM connector terminal B27 and the shift solenoid harness connector, then go to 11.

11.	Clear the DTC with the HDS.

12.	Test-drive the vehicle for several minutes in the D position through all five gears.

13.	Monitor the OBD status for P0713 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail. Does the result indicate PASSED? YES - Troubleshooting is complete.n NO - Return to 1 and recheck.
