DTC Troubleshooting: P0711 (28)
DTC P0711:
ATF Temperature Sensor (Range/Performance)
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information How to Troubleshoot the A/T System.
- 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 in P, 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 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 Initial Inspection and Diagnostic Overview.
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 the ambient air temperature (the Engine Coolant Temperature reads the same as the 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 with the throttle opened at least 4 degrees, and run the vehicle at speeds over 19 mph (30 km/h) cruising for at least 5 minutes.
Or test-drive the vehicle for at least 20 seconds while the ATF temperature reads-4 °F to 230 °F (-20 °C to 110 °C) by monitoring with the HDS. Slow down, and stop the wheels.
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 Initial Inspection and Diagnostic Overview, 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 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 Pending or Confirmed DTCs were indicated in step 12, 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 11. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 9.
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 the ambient air temperature (the Engine Coolant Temperature reads the same as the 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 with the throttle opened at least 4 degrees, and run the vehicle at speeds over 19 mph (30 km/h) cruising for at least 5 minutes.
Or test-drive the vehicle for at least 20 seconds while the ATF temperature reads-4 °F to 230 °F (-20 °C to 110 °C) by monitoring with the HDS. Slow down, and stop the wheels.
18. Check for Pending or Confirmed 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 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 in step 18, 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 15.
