1. Check ATF temperature sensor voltage with the HDS in the A/T data list.
Is ATF temperature 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 sensor and PCM. A
2. Disconnect the ATF temperature sensor connector at the transmission end cover.
3. Check ATF temperature sensor voltage with the HDS.

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 ATF temperature sensor connector terminal No. 2 and body ground.
Is there continuity?
YES-Repair short to ground between PCM connector terminal C3 and the ATF temperature sensor connector terminal No. 2 then, go to step 8.
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.
8. Clear the DTC with the HDS.
9. Test-drive the vehicle for several minutes in the D position in all five gears.
10. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0712.
Did the result indicate a pass?
YES-The problem has been corrected.
NO-Return to step 1 and rechecks
