22. Shift to the P position. Start the engine, and let it

idle.

23. Shift to the D position, and measure the voltage

between PCM connector terminals A18 and A9.

Update the PCM if it does not have the latest

software, or substitute a known-good PCM
(see page 14-11), then recheck. If the symptom/
indication goes away with a known-good PCM,
replace the original PCM.

Replace the output shaft (countershaft) speed

sensor (see page 14-266), then go to step 29.

24. Measure the voltage between PCM connector

terminals A21 and A9.

Repair open in the wire between PCM

connector terminal A21 and the output shaft
(countershaft) speed sensor, then go to step 29.

Go to step 25.

25. Turn the ignition switch OFF.

26. Disconnect PCM connector A (31P).

27. Check for continuity between PCM connector

terminal A21 and body ground.

Repair short to ground in the wire between

PCM connector terminal A21 and the output shaft
(countershaft) speed sensor, then go to step 29.

Check for loose or poor connections at PCM

connector terminal A21. If the connection is OK,
update the PCM if it does not have the latest
software, or substitute a known-good PCM
(see page 14-11), then recheck. If the symptom/
indication goes away with a known-good PCM,
replace the original PCM.

28. Measure the voltage between PCM connector

terminals A18 and A9.

Repair open in the wire between PCM

connector terminal A18 and the output shaft
(countershaft) speed sensor, then go to step 29.

Check for loose or poor connections at PCM

connector terminal A18. If the connection is OK,
update the PCM if it does not have the latest
software, or substitute a known-good PCM
(see page 14-11), then recheck. If the symptom/
indication goes away with a known-good PCM,
replace the original PCM.

29. Clear the DTC with the HDS.

30. Start the engine, run the vehicle in the D position

with the engine speed 2,000 rpm or higher for more
than 10 seconds. Slow down and stop the wheels.

31. Monitor the OBD status for P0722 in the DTCs/

Freeze Data in A/T Mode Menu for a pass/fail.

Trouble shooting is completed.

Return to step 1 and recheck.

Speed Sensor Intermittent Failure

NOTE:

• Record all freeze data and review General

Troubleshooting Information (see page 14-8) before
you troubleshoot.

• This code is caused by an electrical circuit problem

and cannot be caused by a mechanical problem in the
transmission.

1. Clear the DTC with the HDS.

2. Test-drive the vehicle for 10 minutes under the

same conditions as those indicated by the freeze
data, and monitor the OBD status for P0723 in the
DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Go to step 3.

Intermittent failure, the system is OK at this

time. Check for poor connections or loose terminals
at the output shaft (countershaft) speed sensor and
PCM. If the tester indicates NOT COMPLETED,
return to step 2 and recheck.

3. Turn the ignition switch OFF.

4. Disconnect the output shaft (countershaft) speed

sensor connector, and inspect the connector and
connector terminals to be sure they are making
good contact.

Go to step 5.

Repair the connector terminals, then go to

step 5.

5. Connect the output shaft (countershaft) speed

sensor connector.

6. Test-drive the vehicle for several minutes, and

monitor the OBD status for P0723 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.

Go to step 7.

The problem has been corrected. If the tester

indicates NOT COMPLETED, return to step 6 and
recheck.

7. Turn the ignition switch OFF.

8. Jump the SCS line with the HDS.

9. Disconnect PCM connector A (31P).

10. Disconnect the output shaft (countershaft) speed

sensor connector.

11. Check for continuity between output shaft

(countershaft) speed sensor connector terminal
No. 2 and body ground.

Repair short to ground in the wire between

PCM connector terminal A18 and the output shaft
(countershaft) speed sensor, then go to step 18.

Go to step 12.
