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

WARNING: This page is about a different variant/trim than selected.
NOTE:
  • Record all freeze data and review General Troubleshooting Information (see 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. Clear the DTC with the HDS.
  2. Check for proper input shaft (mainshaft) speed sensor installation (see INPUT SHAFT (MAINSHAFT) SPEED SENSOR REPLACEMENT ).
  3. 4WD model: Raise the vehicle, make sure it is securely supported, and allow all four wheels to rotate freely.

    2WD model: Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely. Or raise the vehicle.

  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 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

    Does the result indicate FAILED? 

    1. YES-  Go to step 6.
    2. NO-  If the tester indicates PASSED, intermittent failure, the system is OK at this time. Check for loose or poor connections at the PCM and 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 connector A (31P) and input shaft (mainshaft) speed sensor connector.
  9. Check for continuity between PCM connector terminals A8 and body ground, and between A9 and body ground.

    Is there continuity? 

    1. YES-  Go to step 10.
    2. NO-  Repair open in the wires between PCM connector terminals A8, A9, and ground (G101), or repair poor ground (G101), then go to step  29.
  10. Connect PCM connector A (31P).
  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? 

    1. YES-  Go to step 13.
    2. NO-  Go to step  24.
  13. Turn the ignition switch OFF.
  14. Disconnect PCM connector C (22P).
  15. Check for continuity between input shaft (mainshaft) speed sensor connector terminal No. 2 and body ground.

    Is there continuity? 

    1. YES-  Repair short to ground in the wire between PCM connector terminal C19 and input shaft (mainshaft) speed sensor, then go to step  29.
    2. NO-  Go to step 16.
  16. Check for continuity between input shaft (mainshaft) speed sensor connector terminal No. 3 and body ground.

    Is there continuity? 

    1. YES-  Go to step 17.
    2. NO-  Repair open in the wire between the input shaft (mainshaft) speed sensor connector and ground (G101), then go to step  29.
  17. Connect PCM connector C (22P).
  18. Turn the ignition switch ON (II).
  19. Measure the voltage between input shaft (mainshaft) speed sensor connector terminals No. 2 and No. 3.

    Is there about 5 V? 

    1. YES-  Go to step 20.
    2. NO-  Go to step  28.
  20. Connect the input shaft (mainshaft) speed sensor connector.
  21. Measure the voltage between PCM connector terminals C19 and A9.

    Is there 0 V or about 5 V? 

    1. YES-  Go to step 22.
    2. NO-  Replace the input shaft (mainshaft) speed sensor (see step INPUT SHAFT (MAINSHAFT) SPEED SENSOR REPLACEMENT ), then go to  29.
  22. Shift to the P position. Start the engine, and let it idle.
  23. With the engine idling, measure the voltage between PCM connector terminals C19 and A9.

    Is there 1.5-3.5 V? 

    1. YES-  Update the PCM if it does not have the latest software, or substitute a known-good PCM (see DTC CLEAR PROCEDURE ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
    2. NO-  Replace the input shaft (mainshaft) speed sensor (see step INPUT SHAFT (MAINSHAFT) SPEED SENSOR REPLACEMENT ), then go to  29.
  24. Measure the voltage between PCM connector terminals A20 and A9.
