DTC P0711: Problem in ATF Temperature Sensor Circuit
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information. How To Troubleshoot A/T Systems (A/T)
- 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 outside 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 A/T Stall Speed Test three times, then go to step 3.
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, Service and Repair 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 outside air temperature?
YES - Go to step 5.
NO - Leave the engine off until ECT Sensor reads the same as the outside 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 - Go to step 12.
NO - Replace the ATF temperature sensor, Service and Repair then go to step 6.
6. Clear the DTC with the HDS.
7. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
8. Allow the engine coolant temperature to cool to the outside air temperature.
9. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on), and wait for at least 20 seconds, then drive the vehicle at speeds over 19 mph (31 km/h) for at least 5 minutes.
10. Check for Temporary DTCs or 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 HDS indicate PASSED?
YES - Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step 10, go to the indicated DTC's troubleshooting.
NO - If the HDS indicates FAILED, check for poor connections or loose terminals between the ATF temperature sensor and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 7.
12. Update the PCM if it does not have the latest software, ECM/PCM Update (A/T) or substitute a known-good PCM. Initial Inspection and Diagnostic Overview
13. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
14. Allow the engine coolant temperature to cool to the outside air temperature.
15. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on), and wait for at least 20 seconds, then drive the vehicle at speeds over 19 mph (31 km/h) for at least 5 minutes.
16. Check for Temporary DTCs or 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, Initial Inspection and Diagnostic Overview then go to step 13. If the PCM was substituted, go to step 1.
NO - Go to step 17.
17. Monitor the OBD STATUS for P0711 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?
YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. Service and Repair If any other Temporary DTCs or DTCs were indicated in step 16, go to the indicated DTC's troubleshooting.
NO - If the HDS 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, Initial Inspection and Diagnostic Overview then go to step 13. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 13.
