terminal A24 and output shaft (countershaft) speed
sensor connector terminal No. 3.

Go to step 16.

Repair open in the wire between PCM

connector terminal A24 and output shaft
(countershaft) speed sensor connector, then go to
step 28.

16. Connect PCM connector A (31P).

17. Turn the ignition switch ON (II).

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

idle.

22. 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 28.

23. Measure the voltage between PCM connector

terminals A21 and A9.

Repair open in the wire between PCM

connector A21 and the output shaft (countershaft)
speed sensor, then go to step 28.

Go to step 24.

24. Turn the ignition switch OFF.

25. Disconnect PCM connector A (31P).

26. 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 28.

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.

27. 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 28.

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. Clear the DTC with the HDS.

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

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

30. Monitor the OBD status for P0721 in the DTCs/

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

Troubleshooting is completed.

Return to step 1 and recheck.

Problem in Output Shaft

(Countershaft) Speed Sensor Circuit (No
Signal Input)

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. Raise the front of the vehicle, make sure it is

securely supported, and allow the front wheels to
rotate freely.

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

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

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

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

Go to step 5.

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 3 and recheck.

5. Turn the ignition switch OFF.

6. Jump the SCS line with the HDS.

7. Disconnect PCM connector A (31P) and output shaft

(countershaft) speed sensor connector.

8. Check for continuity between PCM connector

terminals A8 and body ground, and between A9
and body ground.

Go to step 9.

Repair open in the wires between PCM

connector terminals A8, A9, and ground (G101), or
repair poor ground (G101), then go to step 29.

9. Connect PCM connector A (31P).

10. Turn the ignition switch ON (II).

11. Measure the voltage between output shaft

(countershaft) speed sensor connector terminal
No. 1 and body ground.

Go to step 12.

Go to step 24.

12. Turn the ignition switch OFF.

13. Jump the SCS line with the HDS.

Wire side of female terminals

Does the r esult indicate a f ailed?
