DTC P0711: Problem in ATF Temperature Sensor Circuit

NOTE:

Record all freeze data and review General Troubleshooting Information (see 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.

Check the ATF temperature with the HAS in the A/T data list.
Does the ATF temperature exceed an ambient-air temperature?
1. YES - Record the ATF temperature. Leave the engine off for more than 30 minutes, and go to step 2.
2. NO - Record the ATF temperature. Test the stall speed RPM (see STALL SPEED TEST ) three times. Go to step 2 after stall speed testing.
Check the ATF temperature with the HAS.
Did the ATF temperature change?
1. YES - Leave the engine off for more than 30 minutes, and go to step 3.
2. NO - Replace the ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ), then go to step 5.
Check the ECT SENSOR with the HAS.
Is the ECT SENSOR equal to the ambient-air temperature?
1. YES - Go to step 4.
2. NO - Leave the engine off until ECT SENSOR equals ambient-air temperature, then go to step 4.
Check the ATF temperature with the HAS.
Is the ATF temperature almost equal to ECT SENSOR?
1. YES - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ATF temperature sensor and PCM.
2. NO - Replace ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ), then go to step 5.
Clear the DTC with the HAS.
Test-drive the vehicle for several minutes in the D5 position through all five gears.
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?
1. YES - Troubleshooting is complete.
2. NO - Return to step 1 and recheck.
