DTC P0711: Problem in ATF Temperature Sensor Circuit

NOTE:
^ 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 TEMP SENSOR with the HDS in the A/T data list.
Does the ATF temperature exceed ambient-air temperature?
YES - Record the ATF temperature. Leave the engine off for more than 30 minutes, and go to step 2.
NO - Record the ATF temperature. Test the stall speed RPM three times. Go to step 2 after stall speed testing.

2. Check the ATF TEMP SENSOR with the HDS.
Does the ATF temperature change?
YES - Leave the engine off for more than 30 minutes, and go to step 3.
NO - Replace the ATF temperature sensor, then go to step 5.

3. Check the ECT SENSOR with the HDS.
Does the ECT SENSOR read about the same as ambient-air temperature?
YES - Go to step 4.
NO - Leave the engine off until the ECT SENSOR reads the same as ambient-air temperature, then go to step 4.

4. Check the ATF TEMP SENSOR with the HDS.
Does the ATF temperature read about the same as the ECT SENSOR?
YES - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ATF temperature sensor and the PCM.
NO - Replace ATF temperature sensor, then go to step 5.

5. Clear the DTC with the HDS.
6. Test-drive the vehicle for several minutes in the D position through all five gears.
7. Monitor the OBD status for P0711 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate PASSED?
YES - Troubleshooting is complete.
NO - If the PCM was updated and the screen indicates FAILED, substitute a known-good PCM, then return to step 5. If the PCM was substituted and the screen indicates FAILED, return to step 1 and recheck. If the screen indicates NOT COMPLETED, return to step 6.
