P0712
DTC P0712: Short in ATF Temperature Sensor CircuitNOTE:
^ Record all freeze data and review General Troubleshooting Information before you troubleshoot.
^ This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
1. Check the ATF TEMP SENSOR voltage with the HDS in the A/T data list.
Is the ATF TEMP SENSOR voltage 0.07 V or less?
YES - Go to step 2.
NO - Intermittent failure, the system is OK at this time. Check for intermittent short in the wires between the ATF temperature and PCM.
2. Disconnect the shift solenoid harness connector at the shift solenoid valve cover.
3. Check ATF TEMP SENSOR voltage with the HDS.
Is ATF TEMP SENSOR voltage 0.07 V or less?
YES - Go to step 4.
NO - Check for a short to ground in the shift solenoid harness wire in the transmission. If the wire is OK, replace ATF temperature sensor, then go to step 8.
4. Turn the ignition switch OFF.
5. Jump the SCS line with the HDS.
6. Disconnect PCM connector C (22P).
7. Check for continuity between the No. 6 terminal of the shift solenoid harness connector and body ground.
Is there continuity?
YES - Repair short to ground in the wire between PCM connector terminal C14 and the shift solenoid harness connector, then go to step 8.
NO - Check for a short to ground in the shift solenoid harness wire in the transmission. If the wire 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.
8. Clear the DTC with the HDS.
9. Test-drive the vehicle for several minutes in the D position through all five gears.
10. Monitor the OBD status for P0712 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate PASSED?
YES - Troubleshooting is complete.
NO - Return to step 1 and recheck.
