38. Turn the ignition switch to ON (II).
39. Clear the DTC with the HDS.
40. Raise the vehicle on a lift, make sure it is supported
securely (see page 1-10), and allow all four wheels
to rotate freely.
41. Start the engine, disable the VSA by pressing the
VSA OFF button, run the vehicle in D hold the
vehicle speed reaches 12 mph (20 km/h), for at
least 10 seconds when the transmission is not
shifting, then slow down and stop the wheels.
42. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the input shaft (mainshaft) speed
sensor and the PCM, then go to step 1.
Go to step 43.
43. Monitor the OBD STATUS for P0716 or P0717 in the
DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTC or DTCs were indicated on step 42,
go to the indicated DTCs troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the input shaft
(mainshaft) speed sensor and the PCM, then go to
step 1. If the screen indicates NOT COMPLETED, go
to step 41.
44. Update the PCM if it does not have the latest
software (see page 14-8), or substitute a known-
good PCM (see page 14-9).
45. Raise the vehicle on a lift, make sure it is supported
securely (see page 1-10), and allow all four wheels
to rotate freely.
46. Start the engine, disable the VSA by pressing the
VSA OFF button, run the vehicle in D hold the
vehicle speed reaches 12 mph (20 km/h), for at
least 10 seconds when the transmission is not
shifting, then slow down and stop the wheels.
47. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the input shaft (mainshaft) speed
sensor and the PCM. If the PCM was updated,
substitute a known-good PCM (see page 14-9), then
go to step 46. If the PCM was substituted, go to step
1.
Go to step 48.
48. Monitor the OBD STATUS for P0716 or P0717 in the
DTCs MENU with the HDS.
If the PCM was updated, troubleshooting is
complete. If the PCM was substituted, replace the
original PCM (see page 11-205). If any other
Temporary DTCs or DTCs were indicated on step
47, go to the indicated DTCs troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the input shaft
(mainshaft) speed sensor and the PCM. If the PCM
was updated, substitute a known-good PCM
(see page 14-9), then go to step 46. If the PCM was
substituted, go to step 1. If the screen indicates
NOT COMPLETED, go to step 46.

NOTE:
• Before you troubleshoot, record all freeze data and
any on-board snapshot, and review General
Troubleshooting Information (see page 14-4).
• 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 at speeds over 12 mph
(20 km/h) in D through all five gears.
3. Turn the ignition switch to LOCK (0), and repeat the
test-drive in step 2.
4. Monitor the OBD STATUS for P0718 in the DTCs
MENU with the HDS.
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 FAILED, go to step 5. If
the screen indicates NOT COMPLETED, return to
step 2 and recheck.
5. Turn the ignition switch to LOCK (0).
6. Disconnect the input shaft (mainshaft) speed
sensor connector, and inspect the connector and
the connector terminals to be sure they are making
good contact.
Go to step 7.
Repair the connector terminals, then go to
step 7.
7. Connect the input shaft (mainshaft) speed sensor
connector.
8. Test-drive the vehicle at speeds over 12 mph
(20 km/h) in D through all five gears.
9. Turn the ignition switch to LOCK (0), and repeat the
test-drive in step 8.
10. Monitor the OBD STATUS for P0718 in the DTCs
MENU with the HDS.
The problem has been corrected.
If the screen indicates FAILED, go to step 11. If
the screen indicates NOT COMPLETED, return to
step 8 and recheck.
11. Turn the ignition switch to LOCK (0).
12. Jump the SCS line with the HDS.
13. Disconnect PCM connector B (44P).
14. Disconnect the input shaft (mainshaft) speed
sensor connector.
15. Check for continuity between input shaft
(mainshaft) speed sensor connector terminal No. 2
and body ground.
Repair a short to ground in the wire between
PCM connector terminal B39 and the input shaft
(mainshaft) speed sensor connector, then go to
step 24.
Go to step 16.
