DTC P0717: Problem in Input Shaft (Mainshaft) Speed Sensor Circuit (No Signal Input)

NOTE: Record all freeze data and review General Troubleshooting Information before you troubleshoot. This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Record all freeze data, and clear the DTC with the HDS.
2. Check for proper input shaft (mainshaft) speed sensor installation.
3. Raise the front of the vehicle, or lift the vehicle up, make sure it is securely supported, 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 mph (48 km/h) for more than 10 seconds. Slow down and stop the wheels.
5. Monitor the OBD status for P0717 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Go to 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 COMPLETED, return to step 4 and recheck.

6. Turn the ignition switch OFF.
7. Jump the SCS line with 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 ground, and between D16 and body ground.





Is there continuity?
YES - Go to step 10.
NO - Repair an open in the wires between PCM connector terminals A3, D16, and ground (G101, G102), or repair a poor ground (G101, G102), then go to step 31.

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 ground.





Is there about 5 V ?
YES - Go to step 13.
NO - Go to step 25.

13. Turn the ignition switch OFF.
14. Disconnect PCM connector B (24P).
15. Check for continuity between input shaft (mainshaft) speed sensor connector terminal No. 2 and body ground.





Is there continuity?
YES - Repair a short to ground in the wire between PCM connector terminal B10 and the input shaft (mainshaft) speed sensor connector, then go to step 31.
NO - Go to step 16.

16. Disconnect PCM connector C (22P).
17. Check for continuity between PCM connector terminal C12 and input shaft (mainshaft) speed sensor connector terminal No. 3.





Is there continuity?
YES - Go to step 18.
NO - Repair an open in the wire between the input shaft (mainshaft) speed sensor connector and PCM connector terminal C12, then go to step 31.

18. Connect PCM connectors B (24P) and C (22P).
19. Turn the ignition switch ON (II).
20. Measure the voltage between input shaft (mainshaft) speed sensor connector terminals No. 2 and No. 3.





Is there about 5 V?
YES - Go to step 21.
NO - Go to step 30.

21. Connect the input shaft (mainshaft) speed sensor connector.
22. Measure the voltage between PCM connector terminals B10 and A3 or D16.





Is the voltage 0 V or about 5 V?
YES - Go to step 23.
NO - Replace the input shaft (mainshaft) speed sensor, then go to step 31.

23. Shift to the P position. Start the engine, and let it idle.
24. With the engine idling, measure the voltage between PCM connector terminals B10 and A3 or D16.





Is there 1.5 - 3.5 V ?
YES - Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
NO - Replace the input shaft (mainshaft) speed sensor, then go to step 31.

25. Measure the voltage between PCM connector terminals C13 and A3 or D16.





Is there about 5 V?
YES - Repair an open in the wire between PCM connector terminal C13 and the input shaft (mainshaft) speed sensor, then go to step 31.
NO - Go to step 26.

26. Turn the ignition switch OFF.
27. Jump the SCS line with the HDS.
28. Disconnect PCM connector C (22P).
29. Check for continuity between PCM connector terminal C13 and body ground.





Is there continuity?
YES - Repair a short in the wire between PCM connector terminal C13 and the input shaft (mainshaft) speed sensor, then go to step 31.
NO - Check for loose or poor connections at PCM connector terminal C13. If the connection is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, 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 B10 and A3 or D16.





Is there about 5 V?
YES - Repair an open in the wire between PCM connector terminal B10 and the input shaft (mainshaft) speed sensor, then go to step 31.
NO - Check for loose or poor connections at PCM connector terminal B10. If the connection is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, 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, run the vehicle in the D position, and hold the vehicle at speeds over 30 mph (48 km/h) for more than 10 seconds. Slow down and stop the wheels.
33. Monitor the OBD status for P0717 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate PASSED?
YES - Troubleshooting is complete.
NO - Return to step 6 and recheck.
