23. Measure the voltage between transmission range switch connector terminals No. 3 and No. 10. 

Is there voltage? 

YES: Update the PCM if it does not have the latest software, or substitute a known-good 
PCM (see PCM UPDATING & SUBSTITUTION FOR TESTING ), then recheck. If the 
symptom/indication goes away with a known-good PCM, replace the original PCM.  

NO: Repair open in the wire between the transmission range switch and PCM connector

24. Clear the DTC with the HDS, and turn the ignition switch OFF.  

25. Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate 

freely.

27. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0706. 

Did the result indicate a pass? 

YES: The problem has been corrected.  

NO: Return to step 1 and recheck.  

DTC P0711: PROBLEM IN ATF TEMPERATURE SENSOR CIRCUIT 

1. Check the ATF temperature with the HDS. 

Does the ATF temperature exceed the ambient-air temperature? 

YES: Record the ATF temperature. Leave the engine off for more than 30 minutes, and go to 
step 2.  

NO: Record the ATF temperature. Test the stall speed RPM (see STALL SPEED TEST ) 
three times. Go to step 2 after stall speed testing.  

2. Check the ATF temperature with the HDS. 

Did the ATF temperature change? 

YES: Leave the engine off for at least 30 more minutes, and go to step 3.  

NO: Replace ATF temperature sensor (see ATF TEMPERATURE SENSOR TEST & 
REPLACEMENT ), then go to step 5 .  

3. Check the ECT SENSOR with the HDS. 

Is the ECT SENSOR equal to the ambient-air temperature? 

YES: Go to step 4.  

NO: Leave the engine off until ECT sensor equals ambient-air temperature, then go to step 4. 

4. Check the ATF temperature with the HDS. 

Is the ATF temperature almost equal to ECT SENSOR? 

YES: Intermittent failure, the system is OK at this time. Check for poor connections or loose 
terminals at the ATF temperature sensor and PCM.  

NO: Replace ATF temperature sensor (see ATF TEMPERATURE SENSOR TEST & 
REPLACEMENT ), then go to step 5.  

5. Clear the DTC with the HDS.  

6. Test-drive the vehicle for several minutes in the D position in all five gears.  

7. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0711. 

Did the result indicate a pass? 

YES: The problem has been corrected.  

NO: Return to step 1 and recheck.
