P0717 codes, shifting problem, D light flashing.

I do not know which pick-up sensor to replace. Speedometer sensor 28810-PCJ-014 or
Vehicle Speed Sensor 28810-P7W-004. I think there are two of each type on the CVT transmission. I only found one each so far. I replaced one of the 28810-PCJ-014 (short) sensors but problem came back. See:

Hi and thanks for using 2CarPros.

This is not a sensor issue. It is a circuit. I am going to provide the diagnostic flow chart to help you find what is causing the problem. All attached picture correlate with these directions. Also, you will need a good scanner/live data/freeze frame abilities.

DTC P0716: Range/Performance Problem in CVT Input Shaft (Drive Pulley) Speed Sensor Circuit

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

NOTE:
Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information.
This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Check for proper CVT input shaft (drive pulley) speed sensor installation.
4. Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely. Or raise the vehicle on a lift.
5. Start the engine, run the vehicle with the shift lever in D, and keep the vehicle at speeds over 19 mph (30 km/h) for at least 30 seconds. Slow down and stop the wheels.
6. Monitor the OBD STATUS for P0716 or P0717 in the DTCs MENU with the HDS.

Does the HDS indicate FAILED?

YES - Go to step 7.

NO - If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between the CVT input shaft (drive pulley) speed sensor and the PCM. If the HDS indicates NOT COMPLETED, go to step 5.

7. Turn the ignition switch to LOCK (0).
8. Jump the SCS line with the HDS.
9. Disconnect PCM connector C (44P).
10. Check for continuity between PCM connector terminal C40 and body ground, and between PCM connector terminal C44 and body ground.

See pic 1

Is there continuity?

YES - Go to step 11.

NO - Repair open in the wires between PCM connector terminals C40, C44, and ground (G101), or repair poor ground (G101), then go to step 28.

11. Connect PCM connector C (44P).
12. Disconnect the CVT input shaft (drive pulley) speed sensor connector.
13. Turn the ignition switch to ON (II).
14. Measure the voltage between CVT input shaft (drive pulley) speed sensor connector terminal No. 1 and body ground.

See pic 2

Is there about 5 V?

YES - Go to step 18.

NO - Go to step 15.

15. Turn the ignition switch to LOCK (0).
16. Disconnect PCM connector B (44P).
17. Check for continuity between PCM connector terminal B18 and CVT input shaft (drive pulley) speed sensor connector terminal No. 1.

See pic 3

Is there continuity?

YES - Go to step 34.

NO - Repair open in the wire between PCM connector terminal B18 and the CVT input shaft (drive pulley) speed sensor connector, then go to step 28.

18. Turn the ignition switch to LOCK (0).
19. Disconnect PCM connector B (44P).
20. Check for continuity between CVT input shaft (drive pulley) speed sensor connector terminal No. 2 and body ground.

See pic 4

Is there continuity?

YES - Repair short to body ground in the wire between PCM connector terminal B17 and the CVT input shaft (drive pulley) speed sensor connector, then go to step 28.

NO - Go to step 21.

21. Check for continuity between PCM connector terminal B33 and CVT input shaft (drive pulley) speed sensor connector terminal No. 3.

See pic 5

Is there continuity?

YES - Go to step 22.

NO - Repair open in the wire between the CVT input shaft (drive pulley) speed sensor connector and PCM connector terminal B33, then go to step 28.

22. Connect PCM connector B (44P).
23. Turn the ignition switch to ON (II).
24. Measure the, voltage between CVT input shaft (drive pulley) speed sensor connector terminals No. 2 and No. 3.

See pic 6

Is there about 5 V?

YES - Go to step 28.

NO - Go to step 25.

25. Turn the ignition switch to LOCK (0).
26. Disconnect PCM connector B (44P).
27. Check for continuity between PCM connector terminal B17 and CVT input shaft (drive pulley) speed sensor connector terminal No. 2.

See pic 7

Is there continuity?

YES - Go to step 38.

NO - Repair open in the wire between PCM connector terminal B17 and the CVT input shaft (drive pulley) speed sensor connector, then go to step 32.

28. Connect the CVT input shaft (drive pulley) speed sensor connector.
29. Clear the DTC with the HDS.
30. Start the engine, run the vehicle with the shift lever in D, and keep the vehicle at speeds over 19 mph (30 km/h) for at least 30 seconds. Slow down and stop the wheels.
31. Monitor the OBD STATUS for P0716 or P0717 in the DTCs MENU with the HDS.

Does the HDS indicate FAILED?

YES - Replace the CVT input shaft (drive pulley) speed sensor, then go to step 32.

NO - Go to step 38.

32. Reconnect all connectors.
33. Turn the ignition switch ON (II).
34. Clear the DTC with the HDS.
35. Start the engine, let it idle for at least 15 seconds. Run the vehicle with the shift lever in D, and keep the vehicle at speeds over 19 mph (30 km/h) for at least 30 seconds. Slow down and stop the wheels.
36. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0716 or P0717 indicated?

YES - Check for poor connections or loose terminals between the CVT input shaft (drive pulley) speed sensor and the. PCM, then go to step 1.

NO - If DTC P0716 or P0717 is not indicated, or if any other Temporary DTCs or DTCs are indicated, go to step 37.

37. Monitor the OBD STATUS for P0716 or P0717 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?

YES - Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step 36, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections or loose terminals between the CVT input shaft (drive pulley) speed sensor and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 35.

38. Update the PCM if it does not have the latest software, or substitute a known-good PCM.
39. Start the engine, let it idle for at least 15 seconds. Run the vehicle with the shift lever in D, and keep the vehicle at speeds over 19 mph (30 km/h) for at least 30 seconds. Slow down and stop the wheels.
40. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0716 or P0717 indicated?

YES - Check for poor connections or loose terminals between the CVT input shaft (drive pulley) speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 39. If the PCM was substituted, go to step 1.

NO - Go to step 41.

41. Monitor the OBD STATUS for P0716 or P0717 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?

YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. If any other Temporary DTCs or DTCs were indicated in step 40, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections or loose terminals between the CVT input shaft (drive pulley) speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 39. If the PCM was substituted, go to step 1. If the HDS indicates not completed, go to step 39.
