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 temperature with the HDS in the A/T data list.

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.

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.

Is the ECT SENSOR equal to the 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 the 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. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.

Is DTC P0711 indicated?

YES - Check for poor connections and loose terminals at the ATF temperature sensor and the PCM, then go to step 1.

NO - Go to step 8.

8. 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. If any other DTCs were indicated on step 7, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections and loose terminals at the ATF temperature sensor and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 6 and recheck.
