33. Start the engine, disable the VSA by pressing the VSA OFF switch, run the vehicle in the D position with

the engine speed 2,000 rpm or higher for at least 10 seconds. Slow down and stop the wheels.

34. Check for DTCs with the HDS.

Is DTC P0721 or P0722 indicated?

YES -Check for poor connections or loose terminals between the output shaft (countershaft) speed sensor
and the PCM, then go to step 1.

NO -Go to step 35.

35. Monitor the OBD STATUS for P0721 or P0722 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -Troubleshooting is complete. If any other DTCs were indicated in step 34, go to the indicated
DTCs troubleshooting.

NO -If the screen 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 screen indicates NOT
COMPLETED, go to step 33.

36. Update the PCM if it does not have the latest software (see UPDATING THE PCM ), or substitute a

known-good PCM (see SUBSTITUTING THE PCM ).

37. Start the engine, disable the VSA by pressing the VSA OFF switch, run the vehicle in the D position with

the engine speed 2,000 rpm or higher for at least 10 seconds. Slow down and stop the wheels.

38. Check for DTCs with the HDS.

Is DTC P0721 or P0722 indicated?

YES -Cheek for poor connections or loose terminals between the output shaft (countershaft) speed sensor
and the PCM. If the PCM was updated, substitute a known-good, PCM (see SUBSTITUTING THE
PCM ), then go to step 37. If the PCM was substituted, go to step 1.

NO -Go to step 39.

39. Monitor the OBD STATUS for P0721 or P0722 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the
original PCM (see ECM/PCM REPLACEMENT ). If any other DTCs were indicated in step 38, go to
the indicated DTCs troubleshooting.

NO -If the screen indicates FAILED, check for poor connections or loose terminals between the output
shaft (countershaft) speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM

(see SUBSTITUTING THE PCM ), then go to step 37. If the PCM was substituted, go to step 1. If the
screen indicates NOT COMPLETED, go to step 37.

DTC P0723: OUTPUT SHAFT (COUNTERSHAFT) SPEED SENSOR INTERMITTENT FAILURE

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Test-drive the vehicle at speeds over 12 mph (20 km/h) in the D position through all five gears.

4. Turn the ignition switch OFF, and repeat the test-drive in step 3.

5. Monitor the OBD STATUS for P0723 in the DTCs MENU with the HDS.

Does the screen indicate FAILED?

YES -Go to step 6.

NO -If the screen 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
screen indicates NOT COMPLETED, go to step 3.

6. Turn the ignition switch OFF.

7. Disconnect the output shaft (countershaft) speed sensor connector, and inspect the connector and

connector terminals to be sure they are making good contact.

Are the connector terminals OK?

YES -Go to step 8.

NO -Repair the connector terminals, then go to step 8.

8. Connect the output shaft (countershaft) speed sensor connector.

9. Test-drive the vehicle at speeds over 12 mph (20 km/h) in the D position through all five gears.

10. Turn the ignition switch OFF, and repeat the test-drive in step 9.

11. Monitor the OBD STATUS for P0723 in the DTCs MENU with the HDS.

Does the screen indicate FAILED?

YES -Go to step 12.

NOTE:



Before you troubleshoot, record all freeze data and any on-board
snapshot, and review General Troubleshooting Information (see GENERAL
TROUBLESHOOTING INFORMATION ).



This code is caused by an electrical circuit problem and cannot be caused
by a mechanical problem in the transmission.
