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 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 (see «STALL SPEED TEST»(ref-220581-S12933755092006022000000) ) three times. Go to step 2 after stall speed testing.
- Check the ATF temperature with the HDS. Did the ATF temperature change? YES- Leave the engine off for at least 30 minutes, and go to step 3. NO- Replace ATF temperature sensor (see step «ATF TEMPERATURE SENSOR TEST/REPLACEMENT»(ref-220581-S38737603842006022000000) ), then go to 5 .
- 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.
- 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 (see «ATF TEMPERATURE SENSOR TEST/REPLACEMENT»(ref-220581-S38737603842006022000000) ), then go to step 5.
- Clear the DTC with the HDS.
- Test-drive the vehicle for several minutes in the D position through all four gears.
- Monitor the OBD status for P0711 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail. Does the result indicate PASSED? YES- Troubleshooting is complete. NO- Return to step 1 and recheck.
