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 (see page 14-3).
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.
Record the ATF temperature. Leave the
engine off for at least 30 minutes, then go to step 3.
Record the ATF temperature. Test the stall
speed RPM (see page 14-210) three times, then go
to step 3.
3. Check the ATF Temp Sensor in the Data List with the HDS.
Leave the engine off for at least 30 minutes,
then go to step 4.
Replace the ATF temperature sensor
(see page 14-229), then go to step 6.
4. Check the ECT Sensor in the Data List with the HDS.
Go to step 5.
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.
Go to step 13.
Replace the ATF temperature sensor
(see page 14-229), then go to step 6.
6. Turn the ignition switch to ON (II).
7. Clear the DTC with the HDS.
8. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
9. Allow the engine coolant temperature to cool to the outside air temperature.
10. 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 31 km/h (19 mph) for at least
5 minutes.
11. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals between the ATF temperature sensor and
thePCM,thengotostep1.
Go to step 12.

13. Update the PCM if it does not have the latest software (see page 11-227), or substitute a known-
good PCM (see page 11-7).
14. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
15. Allow the engine coolant temperature to cool to the outside air temperature.
16. 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 31 km/h (19 mph) for at least
5 minutes.
17. Check for Temporary DTCs or DTCs with the HDS.
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 (see page 11-7), then go to step
14. If the PCM was substituted, go to step 1.
Go to step 18. 18. Monitor the OBD STATUS for P0711 in the DTCs
MENU with the HDS.
If the PCM was updated, troubleshooting is
complete. If the PCM was substituted, replace the
original PCM (see page 11-228). If any other
Temporary DTCs or DTCs were indicated in step 17,
go to the indicated DTC’s troubleshooting.
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 (see page
11-7), then go to step 14. If the PCM was substituted,
go to step 1. If the HDS indicates NOT COMPLETED,
go to step 14.
