DTC P0712: | Short in ATF Temperature Sensor Circuit |
1. | Check the ATF temperature sensor voltage with the HDS in the A/T data list. Is the ATF temperature sensor voltage 0.07 V or less? YES - Go to 2. NO - Intermittent failure, the system is OK at this time. Check for an intermittent short in the ATFT wire between the ATF temperature sensor and the PCM.n |
2. | Disconnect the shift solenoid harness connector at the shift solenoid valve cover. |
3. | Check the ATF temperature sensor voltage with the HDS. Is the ATF temperature sensor voltage 0.07 V or less? YES - Go to 4. NO - Replace ATF temperature sensor, then go to 9. |
4. | Turn the ignition switch OFF. |
5. | Jump the SCS line with the HDS. |
6. | Disconnect PCM connector B (44P). |
7. | Check for continuity between shift solenoid harness connector terminal No. 6 and body ground.
Is there continuity? YES - Repair short to ground in the wire between PCM connector terminal B27 and shift solenoid harness connector terminal No. 6, then go to 9. NO - Go to 8. |
8. | Remove the shift solenoid harness connector, and check for continuity between shift solenoid harness connector terminal No. 6 and body ground. Do not disconnect shift solenoid valve A connector.
Is there continuity? YES - ATF temperature sensor wire shorted out. Replace the shift solenoid harness connector, then go to 9. NO - 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 |
9. | Clear the DTC with the HDS. |
10. | Test-drive the vehicle for several minutes in the D position through all five gears. |
11. | Monitor the OBD status for P0712 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. |
