1. Turn the ignition switch ON (II).
2. Check the ATF TEMP SENSOR in the DATA LIST 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, then go to step 3.
NO - Record the ATF temperature. Test the stall speed RPM three times. Go to step 3 after stall speed testing.

3. Check the ATF TEMP SENSOR in the DATA LIST with the HDS.
Does the ATF temperature change?
YES - Leave the engine off for more than 30 minutes, then go to step 4.
NO - Replace the ATF temperature sensor, then go to step 6.

4. Check the ECT SENSOR in the DATA LIST with the HDS.
Does the ECT SENSOR read about the same as the ambient air temperature?
YES - Go to step 5.
NO - Leave the engine off until ECT SENSOR reads the some as the ambient air temperature, then go to step 5.

5. Check ATF TEMP SENSOR in the DATA LIST with the HDS.
Does the ATF temperature read about the same as 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 6.

6. Reconnect all connectors.
7. Turn the ignition switch ON (II).
8. Clear the DTC with the HDS.
9. Test-drive the vehicle for several minutes in the D position through all five gears.
10. Check for DTCs with the HDS.
Is DTC P0711 indicated?
YES - Check for poor connections or loose terminals between the ATF temperature sensor and the PCM, then go to step 1.
NO - Go to step 11.

11. Monitor the OBD STATUS for P0711 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES - Troubleshooting is complete. If any other DTCs were indicated in step 10, go to the indicated DTC's troubleshooting.
NO - If the screen indicates FAILED, check for poor connections or loose terminals between the ATF temperature sensor and the PCM, then go to step 1. If the screen indicates NOT COMPLETED, go to step 9.
