15. Clear the DTC with the HDS.

16. Start the engine, disable the VSA by pressing the

VSA OFF switch (if equipped), run the vehicle with
the shift lever in D until the vehicle speed reaches
40 km/h (25 mph), then slow down and stop the
wheels.

17. Monitor the OBD STATUS for P0706 in the DTCs

MENU with the HDS.

Go to step 18.

If the HDS indicates PASSED, intermittent

failure, the system is OK at this time. Check for
poor connections or loose terminals between the
transmission range switch and the PCM. If the HDS
indicates NOT COMPLETED, go to step 16.

18. Turn the ignition switch to LOCK (0).

19. Disconnect the transmission range switch

connector.

20. Check for continuity between transmission range

switch connector terminal No. 10 and body ground.

Go to step 21.

Repair open in the wire between the

transmission range switch and body ground (G101)
(see page 22-16), or repair poor body ground
(G101), then go to step 25.

21. Turn the ignition switch to ON (II).

22. Measure the voltage between transmission range

switch connector terminals No. 5 and No. 10.

Go to step 23.

Repair open in the wire between the

transmission range switch and PCM connector
terminal B28, then go to step 25.

23. Measure the voltage between transmission range

switch connector terminals No. 8 and No. 10.

Go to step 24.

Repair open in the wire between the

transmission range switch and PCM connector
terminal B21, then go to step 25.

24. Measure the voltage between transmission range

switch connector terminals No. 3 and No. 10.

Go to step 31.

Repair open in the wire between the

transmission range switch and PCM connector
terminal B15, then go to step 25.

25. Reconnect all connectors.

26. Turn the ignition switch to ON (II).

27. Clear the DTC with the HDS.

28. Start the engine, disable the VSA by pressing the

VSA OFF switch (if equipped), run the vehicle with
the shift lever in D until the vehicle speed reaches
48 km/h (30 mph), then slow down and stop the
wheels.

29. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals between the transmission range switch
and the PCM, then go to step 1.

Go to step 30.

30. Monitor the OBD STATUS for P0706 in the DTCs

MENU with the HDS.

Troubleshooting is complete. If any other

Temporary DTCs or DTCs were indicated in step 29,
go to the indicated DTC’s troubleshooting.

If the HDS indicates FAILED, check for poor

connections or loose terminals between the
transmission range switch and the PCM, then go to
step 1. If the HDS indicates NOT COMPLETED, go to
step 28.

31. Reconnect all connectors.

32. 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).

33. Start the engine, disable the VSA by pressing the

VSA OFF switch (if equipped), run the vehicle with
the shift lever in D until the vehicle speed reaches
48 km/h (30 mph), then slow down and stop the
wheels.

34. Check for Temporary DTCs or DTCs with the HDS.

Check for poor connections or loose

terminals between the transmission range switch
and the PCM. If the PCM was updated, substitute a
known-good PCM (see page 11-7), then go to step
33. If the PCM was substituted, go to step 1.

Go to step 35.

35. Monitor the OBD STATUS for P0706 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 34,
go to the indicated DTC’s troubleshooting.

If the HDS indicates FAILED, check for poor

connections or loose terminals between the
transmission range switch and the PCM. If the PCM
was updated, substitute a known-good PCM
(see page 11-7), then go to step 33. If the PCM was
substituted, go to step 1. If the HDS indicates NOT
COMPLETED, go to step 33.

DTC P0711:

YES

14-96

Automatic Transmission

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
the PCM, then go to step 1.

Go to step 12.

Does the AT F temper atur e exceed the outside air
temper atur e?

Did the AT F temper atur e change?

Does the ECT Sensor r ead about the same as the
outside air temper atur e?

Does the AT F temper atur e r ead about the same as
ECT Sensor ?

Is DT C P07 11 indicated?
