DTC P0717: Problem in CVT Input Shaft (Drive Pulley) Speed Sensor Circuit (No Signal Input)
2005 Model

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. Start the engine, and press the brake pedal securely.
2. Shift to the D position, and let the engine idle.
3. Check the DRIVE PULLEY with the HDS in the data list.
Is the DRIVE PULLEY 128 rpm or less?
YES- Go to step 4.
NO- Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the CVT input shaft (drive pulley) speed sensor and TCM.
4. Turn the ignition switch OFF.





5. Check for continuity between TCM connector terminals A4 and body ground, and between A17 and body ground.
Is there continuity?
YES- Go to step 6.
NO- Repair open in the wires between TCM connector terminals A4, A17, and ground (G101), or repair poor ground (G101).
6. Disconnect CVT input shaft (drive pulley) speed sensor connector.
7. Turn the ignition switch ON (II).





8. Measure the voltage between CVT input shaft (drive pulley) speed sensor connector terminal No. 1 and body ground.
Is there about 5 V?
YES- Go to step 9.
NO- Go to step 19.
9. Turn the ignition switch OFF.





10. Check for continuity between CVT input shaft (drive pulley) speed sensor connector terminal No. 2 and body ground.
Is there continuity?
YES- Repair short to ground in the wire between TCM connector terminal B10 and the CVT input shaft (drive pulley) speed sensor.
NO- Go to step 11.





11. Check for continuity between CVT input shaft (drive pulley) speed sensor connector terminal No. 3 and body ground.
Is there continuity?
YES- Go to step 12.
NO- Repair loose terminal or open in the wire between TCM connector terminal B17 and the CVT input shaft (drive pulley) speed sensor.
12. Turn the ignition switch ON (II).





13. Measure the voltage between CVT input shaft (drive pulley) speed sensor connector terminals No. 2 and No. 3.
Is there about 5 V?
YES- Go to step 14.
NO- Go to step 25.
14. Connect CVT input shaft (drive pulley) speed sensor connector.





15. Measure the voltage between TCM connector terminals B10 and B17.
Is there about 0 V or about 5 V?
YES- Go to step 16.
NO- Replace the CVT input shaft (drive pulley) speed sensor, then go to step 26.
16. Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely.
17. Start the engine, shift to the D position, and let the engine idle.





18. Measure the voltage between TCM connector terminals B10 and B17.
Is there 1.5 - 3.5 V?
YES- Check for loose or poor connections at TCM connector terminals B10 and B17. If the connections are OK, substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM.
NO- Replace the CVT input shaft (drive pulley) speed sensor, then go to step 26.
19. Turn the ignition switch OFF.
20. Disconnect TCM connector B (22P).





21. Check for continuity between CVT input shaft (drive pulley) speed sensor connector terminal No. 1 and body ground.
Is there continuity?
YES- Repair short to ground in the wire between TCM connector terminal B22 and the CVT input shaft (drive pulley) speed sensor.
NO- Go to step 22.
22. Connect TCM connector B (22P).
23. Turn the ignition switch ON (II).





24. Measure the voltage between TCM connector terminals B22 and A4 or A17.
Is there about 5 V?
YES- Repair open in the wire between TCM connector terminal B22 and the CVT input shaft (drive pulley) speed sensor.
NO- Check for loose or poor connections at TCM connector terminal B22. If the connection is OK, substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM.





25. Measure the voltage between TCM connector terminals B10 and B17.
Is there about 5 V?
YES- Repair open in the wire between TCM connector terminal B10 and the CVT input shaft (drive pulley) speed sensor.
NO- Check for loose or poor connections at TCM connector terminal B10. If the connection is OK, substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM.
26. Clear the DTC with the HDS.
27. Test-drive the vehicle for several minutes under the same conditions as those indicated by the freeze data.
28. Check that DTC P0717 recurs.
Is DTC P0717 indicated?
YES- Return to step 1 and recheck.
NO- The problem has been corrected.
