P0717
DTC P0717: 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, make sure it is securely supported, and allow the front wheels to rotate freely.
4. Start the engine, drive the vehicle in the D position, and hold the vehicle at speeds over 30 mph (48 km/h)m for more than 10 seconds. Slow down and stop the wheels.
5. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0717.
Did the result indicate a fail?
YES-Go to step 6.
NO-Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the input shaft (mainshaft) speed sensor. If the tester indicates NOT COMPLETE, return to step 4 and rechecks
6. Turn the ignition switch OFF.
7. Jump the SCS line with the HDS.
8. Disconnect PCM connectors B (24P) and E (31P), and the input shaft (mainshaft) speed sensor connector.
9. Check for continuity between PCM connector terminals B15 and body ground, and between E3 and body ground.
Is there continuity?
YES-Go to step 10.
NO-Repair open in the wire between PCM connector terminals B15, E3, and ground (G101, G102), or repair poor ground (G101, G102), then go to step 30.
10. Connect PCM connectors B (24P) and E (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?
YES-Go to step 13.
NO-Go to step 24.
13. Turn the ignition switch OFF.
14. Jump the SCS line with the HDS.
15. Disconnect PCM connector D (17P).
16. Check for continuity between input shaft (mainshaft) speed sensor connector terminal No. 2 and body ground.
Is there continuity?
YES-Repair short to ground in the wire between PCM connector terminal D8 and input shaft (mainshaft) speed sensor, then go to step 31.
NO-Go to step 17.
17. Check for continuity between input shaft (mainshaft) speed sensor connector terminal No. 3 and PCM connector terminal D10.
Is there continuity?
YES-Go to step 17.
NO-Repair open in the wire between the input shaft (mainshaft) speed sensor connector and PCM connector terminal D10, then go to step 31.
18. Connect PCM connector D (17P).
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 D8 and E15 or E3.
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 D8 and B15 or E3.
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 D12 and B15 or E3.
Is there about 5 V?
YES-Repair open in the wire between PCM connector terminal D12 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 D (17P).
29. Check for continuity between PCM connector terminal D12 and body ground.
Is there continuity?
YES-Repair short to ground in the wire between PCM connector terminal D12 and the input shaft (mainshaft) speed sensor, then go to step 31.
NO-Check for loose or poor connections at PCM connector terminal D12. 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 D8 and B15 or E3.
Is there about 5 V ?
YES-Repair open in the wire between PCM connector terminal D8 and the input shaft (mainshaft) speed sensor, then go to step 31.
NO-Check for loose or poor connections at PCM connector terminal D8. 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. Test-drive the vehicle for several minutes under the same conditions as those indicated by the freeze data.
33. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0717.
Did the result indicate a pass?
YES-The problem has been corrected.
NO-Return to step 1 and recheck.
