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 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 at least 30 minutes, then 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 TEMP SENSOR in the DATA LIST with the HDS.

Did the ATF temperature change?

YES - Leave the engine off for at least 30 minutes, then go to step 3.

NO - Replace the ATF temperature sensor, then go to step 5.

3. 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 4.

NO - Leave the engine off until the ECT sensor equals the ambient-air temperature, then go to step 4.

4. Check the ATF TEMP SENSOR in the DATA LIST 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 - Go to step 5.

5. Replace the ATF temperature sensor.
6. Reconnect all connectors.
7. Turn the ignition switch to ON (II).
8. Clear the DTC with the HDS.
9. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
10. Turn the ignition switch to LOCK (0), and allow the engine coolant temperature to cool to the ambient air temperature.
11. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on). Wait for at least 20 seconds, then drive the vehicle at speeds over 19 mph (31 km/h) for at least 5 minutes.
12. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0711 indicated?

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

NO - If Temporary DTC or DTC P0711 is not indicated, or if any other Temporary DTCs are indicated, go to step 11.

13. 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 Temporary DTC or DTCs were indicated on step 10, go to the indicated DTCs troubleshooting.

NO - If the screen indicates FAILED, check for poor connections or loose terminals at the ATF temperature sensor and the PCM, then go to step 1. If the screen indicates NOT COMPLETED, go to step 9.
