NOTE:
^ 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 temperature with the HDS.
Does the ATF temperature exceed the 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 temperature with the HDS.
Did the ATF temperature change?
YES: Leave the engine off for at least 30 more minutes, and go to step 3.
NO: Replace ATF temperature sensor, then go to step 5.
3. Check the ECT SENSOR with the HDS.
Is the ECT SENSOR equal to the ambient-air temperature?
YES: Go to step 4.
NO: Leave the engine off until ECT sensor equals ambient-air temperature, then go to step 4.
4. Check the ATF temperature with the HDS.
Is the ATF temperature almost equal to 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 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 in all five gears.
7. Check the OBD status in DTC Monitor Tool from DTCs/Freeze Data in A/T Mode Menu for a pass/fail test of code P0711.
Did the result indicate a pass?
YES: The problem has been corrected.
NO: Return to step 1 and recheck.
