15. Clear the DTC with the HDS.
16. Start the engine, disable the VSA by pressing theVSA 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 (G 101)
(see page 22-16), or repair poor body ground
(G101), then go to step 25.

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.
