DTC Troubleshooting: P0711
DTC P0711: ATF Temperature Sensor (Range/Performance)
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information. How To Troubleshoot A/T Systems
- 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), and wait for 20 seconds.
2. Check the ATF Temperature with the HDS in the A/T Data List.
Does the ATF Temperature indicate -4 °F (-20 °C) or below?
YES - Go to step 3.
NO - Go to step 5.
3. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
4. Check the ATF Temperature with the HDS in the A/T Data List.
Does the ATF Temperature remain -4 °F (-20 °C) or below?
YES - Replace the ATF temperature sensor, Service and Repair then go to step 14.
NO - Intermittent failure, the system is OK at this time. If there is an abnormal temperature rise in the ATF temperature sensor, go to step 8.
5. Check that the ATF Temperature with the HDS in the A/T Data List.
Does the ATF Temperature exceed 230 °F (110 °C)?
YES - Go to step 6.
NO - Intermittent failure, the system is OK at this time.
6. Leave the engine off until the Engine Coolant Temperature reads 122 °F (50 °C) with the HDS in the A/T Data List.
7. Check the ATF Temperature with the HDS in the A/T Data List.
Does the ATF temperature remain 230 °F (110 °C) or higher?
YES - Replace the ATF temperature sensor, Service and Repair then go to step 14.
NO - Intermittent failure, the system is OK at this time. If there is an abnormal decrease in temperature of the ATF temperature sensor, go to step 8.
8. Update the A/T software in the PCM if it does not have the latest software, PCM Update or substitute a known-good PCM. Reading and Clearing Diagnostic Trouble Codes
9. Turn the ignition switch to ON (II), and wait for 20 seconds, then start the engine. Warm the engine up to normal operating temperature (the radiator fan comes on).
10. Turn the engine off, and leave it off until the engine coolant cools to ambient air temperature (the Engine Coolant Temperature reads the same as ambient air temperature with the HDS).
11. Turn the ignition switch to ON (II), and wait for 20 seconds, then start the engine. Warm the engine up to normal operating temperature (the radiator fan comes on). Start off in D, accelerate at 4-degree-opened throttle or more opened throttle, and run the vehicle at speeds over 19 mph (30 km/h) for at least 5 minutes.
12. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0711 indicated?
YES - If the PCM was updated, substitute a known-good PCM, Reading and Clearing Diagnostic Trouble Codes then recheck. If the PCM was substituted, go to step 1.
NO - Go to step 13.
13. Monitor the OBD STATUS for P0711 in the DTCs MENU with the DHS.
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 Pending or Confirmed DTCs were indicated on step 12, go to the indicated DTC's troubleshooting.
NO - Check for poor connections and loose terminals at the ATF temperature sensor and the PCM. If the PCM was updated, substitute a known-good PCM, Reading and Clearing Diagnostic Trouble Codes then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 9 and recheck.
14. Clear the DTC with the HDS.
15. Turn the ignition switch to ON (II), and wait for 20 seconds, then start the engine. Warm the engine up to normal operating temperature (the radiator fan comes on).
16. Turn the engine off, and leave it off until the engine coolant cools to ambient air temperature (the Engine Coolant Temperature reads the same as ambient air temperature with the HDS).
17. Turn the ignition switch to ON (II), and wait for 20 seconds, then start the engine. Warm the engine up to normal operating temperature (the radiator fan comes on). Start off in D, accelerate at 4-degree-opened throttle or more opened throttle, and run the vehicle at speeds over 19 mph (30 km/h) for at least 5 minutes.
18. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0711 indicated?
YES - Check for poor connections and loose terminals at the ATF temperature sensor and the PCM, then 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 HDS indicate PASSED?
YES - Troubleshooting is complete. If any other Pending or Confirmed DTCs were indicated on step 18, go to the indicated DTC's troubleshooting.
NO - Check for poor connections and loose terminals at the ATF temperature sensor and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 15 and recheck.
