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. Check for proper output shaft (countershaft) speed sensor installation (see page 14-227).
2. Turn the ignition switch to ON (II).
3. Clear the DTC with the HDS.
4. Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to
rotate freely, or raise the vehicle on a lift.
5. Start the engine, disable the VSA by pressing the VSA OFF switch (if equipped), run the vehicle with
the shift lever in D and the engine speed 2,000 rpm
or higher, for at least 10 seconds. Slow down and
stop the wheels.
6. Monitor the OBD STATUS for P0721 or P0722 in the DTCs MENU with the HDS.
Go to step 7.
If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. Check for
poor connections or loose terminals between the
output shaft (countershaft) speed sensor and the
PCM. If the HDS indicates NOT COMPLETED, go to
step 5. 7. Turn the ignition switch to LOCK (0).
8. Jump the SCS line with the HDS.
9. Disconnect PCM connector C (44P).
10. Check for continuity between PCM connector terminal C40 and body ground, and between PCM
connector terminal C44 and body ground.
Go to step 11.
Repair open in the wires between PCM
connector terminals C40, C44, and body ground
(G101) (see page 22-16), or repair poor body
ground (G 101), then go to step 26.

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. Clear the DTC with the HDS.
3. Test-drive the vehicle with the shift lever in D, and let the transmission shift through all five gears with
the engine speed at 2,000 rpm or higher.
4. Monitor the OBD STATUS for P0723 in the DTCs MENU with the HDS.
Go to step 5.
If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. Check for
poor connections or loose terminals between the
output shaft (countershaft) speed sensor and the
PCM. If the HDS indicates NOT COMPLETED, go to
step 3.
5. Turn the ignition switch to LOCK (0).
6. 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 7.
Repair the connector terminals, then go to
step 23. 7. Jump the SCS line with the HDS.
8. Disconnect PCM connector C (44P).
9. Check for continuity between PCM connector
terminal C40 and body ground, and between PCM
connector terminal C44 and body ground.
Go to step 10.
Repair open in the wires between PCM
connector terminals C40, C44, and body ground
(G101) (see page 22-16), or repair poor body
ground (G 101), then go to step 23.

Check for poor connections or loose
terminals between the output shaft (countershaft)
speed sensor and the PCM, then go to step 1.
Go to step 28.
28. Monitor the OBD STATUS for P0723 in the DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 27,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor
connections or loose terminals between the output
shaft (countershaft) speed sensor and the PCM,
then go to step 1. If the HDS indicates NOT
COMPLETED, go to step 26.
