DTC P0711: Problem in ATF Temperature Sensor CircuitNOTE:
^ 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. Turn the ignition switch to 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 at least 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.
Did the ATF temperature change?
YES - Leave the engine off for at least 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.
Is the ECT SENSOR reading about the same as the ambient air temperature?
YES - Go to step 5.
NO - Leave the engine off until ECT SENSOR reads the same as the ambient air temperature, then go to step 5.
5. Check the 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 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 ambient temperature.
11. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on). Let the engine idle for at least another 20 seconds, then test-drive the vehicle at speeds over19 mph (31 km/h) for 5 minutes or more.
12. 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 13.
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 DTCs were indicated in step 12, 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.
14. Update the PCM if it does not have the latest software, or substitute a known-good PCM.
15. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
16. Turn the ignition switch to LOCK (0), and allow the engine coolant temperature to cool to ambient temperature.
17. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on). Let the engine idle for at least another 20 seconds, then test-drive the vehicle at speeds over 19 mph (31 km/h) for 5 minutes or more.
18. 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. If the PCM was updated, substitute a known-good PCM, then go to step 15. If the PCM was substituted, go to step 1.
NO - Go to step 19.
19. Monitor the OBD STATUS for P0711 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. If any other DTCs were indicated in step 18, 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. If the PCM was updated, substitute a known-good PCM, then go to step 15. If the PCM was substituted, go to step 1. If the screen indicates NOT COMPLETED, go to step 15.
