DTC P0717: Problem in Input Shaft
(Mainshaft) Speed Sensor Circuit (No Signal
Input)
NOTE:
• Record all freeze data and review General
Troubleshooting Information (see page 14-4) before
y o u troubleshoot.
• This code is caused by an electrical circuit p r o b l e m
and cannot be caused by a mechanical p r o b l e m in the
transmission.
1. Record all freeze data, and clear the DTC w i t h the
HDS.
2. Check for proper input shaft (mainshaft) speed
sensor installation (see page 14-223).
3. Raise the front of the vehicle, or lift the vehicle up,
make sure it is securely s u p p o r t e d , and allow the
front wheels to rotate freely.
4. Start the engine, run the vehicle in the D position,
and hold the vehicle at speeds over 30 m p h
(48 km/h) for more than 10 seconds. Slow d o w n
and stop the wheels.
5. M o n i t o r the OBD status for P0717 in the DTCs/
Freeze Data in A/T Mode M e n u for a pass/fail.
Does the result indicate a fail?
Y E S — G o t o step 6.
NO—Intermittent failure, the system is OK at this
time. Check for loose or poor connections at the
PCM and the input shaft (mainshaft) speed sensor
connectors. If the tester indicates NOT COMPLETE,
return to step 4 and recheck. •
6. Turn the ignition switch OFF.
7. J u m p the SCS line w i t h the HDS.
8. Disconnect PCM connectors A (31P) and D (17P),
and the input shaft (mainshaft) speed sensor
connector.
9. Check for continuity between PCM connector
terminals A3 and body g r o u n d , and between D16
and body g r o u n d .

Is there continuity?
Y E S — G o to step 10.
NO—Repair an open in the w i r e s between PCM
connector terminals A 3 , D16, and g r o u n d (G101,
G102), or repair a poor g r o u n d (G101, G102), then
go to step 3 1 .
10. Connect PCM connectors A (31P) and D (17P).
11. Turn the ignition switch ON (II).
12. Measure the voltage between input shaft
(mainshaft) speed sensor connector terminal No. 1
and body g r o u n d .
