5. Monitor the OBD STATUS for P0718 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 at the input shaft (mainshaft) speed sensor and the PCM. If the screen
indicates NOT COMPLETED, go to step 3.

6. Turn the ignition switch OFF.

7. Disconnect the input shaft (mainshaft) 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 input shaft (mainshaft) 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 P0718 in the DTCs MENU with the HDS.

Does the screen indicate FAILED?

YES -Go to step 12.

NO -If the screen indicates PASSED, troubleshooting is complete. If the screen indicates NOT
COMPLETED, go to step 9.

12. Turn the ignition switch OFF.

13. Jump the SCS line with the HDS.

14. Disconnect PCM connector C (22P).

15. Disconnect the input shaft (mainshaft) speed sensor connector.

16. Check for continuity between input shaft (mainshaft) speed sensor connector terminal No. 2 and body

ground.

Is there continuity?

YES -Repair short to body ground in the wire between PCM connector terminal C19 and the input shaft
(mainshaft) speed sensor, then go to step 23.

NO -Go to step 17.

17. Connect PCM connector C (22P).

18. Turn the ignition switch ON (II).

19. Measure the voltage between input shaft (mainshaft) speed sensor connector terminal No. 2 and body

ground.

Is there continuity?

YES -Go to step 30.

NO -Repair open in the wire between PCM connector terminal C19 and the input shaft (mainshaft) speed
sensor, then go to step 23.

23. Reconnect all connectors.

24. Turn the ignition switch ON (II).

25. Clear the DTC with the HDS.

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

27. Turn the ignition switch OFF, and repeat the test-drive in step 26.

28. Check for DTCs with the HDS.

Is DTC P0718 indicated?

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

NO -Go to step 29.

29. Monitor the OBD STATUS for P0718 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -Troubleshooting is complete. If any other DTCs were indicated in step 28, go to the indicated
DTC's troubleshooting.

NO -If the screen indicates FAILED, check for poor connections or loose terminals between the input
shaft (mainshaft) speed sensor and the PCM, then go to step 1. If the screen indicates NOT
COMPLETED, go to step 26.

30. 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 ).

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

32. Turn the ignition switch OFF, and repeat the test-drive in step 31.

33. Check for DTCs with the HDS.

Is DTC P0718 indicated?

YES -Check for poor connections or loose terminals between the input shaft (mainshaft) speed sensor and
the PCM. If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ),
then go to step 31. If the PCM was substituted, go to step 1.

NO -Go to step 34.

34. Monitor the OBD STATUS for P0718 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 33, go to
the indicated DTC's troubleshooting.

NO -If the screen indicates FAILED, check for poor connections or loose terminals between the input
shaft (mainshaft) speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM (see
SUBSTITUTING THE PCM ), then go to step 31. If the PCM was substituted, go to step 1. If the
screen indicates NOT COMPLETED, go to step 31.

DTC P0721: PROBLEM IN OUTPUT SHAFT (COUNTERSHAFT) SPEED SENSOR CIRCUIT; DTC

SIGNAL INPUT)

1. Turn the ignition switch ON (II).

NOTE:



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