29. Check for continuity between PCM connector
terminal A20 and body ground.
Repair short to ground in the wire between
PCM connector terminal A20 and the input shaft
(mainshaft) speed sensor connector, then go to
step 31.
Check for loose or poor connections at PCM
connector terminal A20. 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.
30. Measure the voltage between PCM connector
terminals C19 and A9.
Repair open in the wire between PCM
connector terminal C19 and the input shaft
(mainshaft) speed sensor connector, then go to
step 31.
Check for loose or poor connections at PCM
connector terminal C19. 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.
31. Clear the DTC with the HDS.
32. Start the engine, drive the vehicle in the D position,
and hold the vehicle at speeds over 30 mph (48
km/h) for more than 10 seconds.
33. Monitor the OBD status for P0717 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
Troubleshooting is completed.
Return to step 1 and recheck.

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 several minutes in the D
position through all five gears.
3. Monitor the OBD status for P0718 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
Go to step 4.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the input shaft (mainshaft) speed sensor and
PCM. If the tester indicates NOT COMPLETED,
return to step 2 and recheck.
4. Turn the ignition switch OFF.
5. Disconnect the input shaft (mainshaft) speed
sensor connector, and inspect the connector and
connector terminals to be sure they are making
good contact.
Go to step 6.
Repair the connector terminals, then go to
step 6.
6. Connect the input shaft (mainshaft) speed sensor
connector.
7. Test-drive the vehicle for several minutes, and
monitor the OBD status for P0718 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
Go to step 8.
The problem has been corrected. If the tester
indicates NOT COMPLETED, return to step 7 and
recheck.
8. Turn the ignition switch OFF.
9. Jump the SCS line with the HDS.
10. Disconnect PCM connector C (22P).
11. Disconnect the input shaft (mainshaft) speed
sensor connector.
12. Check for continuity between input shaft
(mainshaft) speed sensor connector terminal No. 2
and body ground.
Repair short to ground in the wire between
PCM connector terminal C19 and the input shaft
(mainshaft) speed sensor connector, then go to
step 19.
Go to step 13.

13. Connect PCM connector C (22P).
14. Turn the ignition switch ON (II).
15. Measure the voltage between input shaft

and body ground.
Replace the input shaft (mainshaft) speed
sensor (see page 14-266), then go to step 19.
Go to step 16.
16. Turn the ignition switch OFF.
17. Disconnect PCM connector C (22P).
18. Check for continuity between PCM connector
terminal C19 and input shaft (mainshaft) speed
sensor connector terminal No. 2.
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/

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

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
