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.
