DTC Troubleshooting: P0716 (15-5)
| DTC P0716: | Problem in Mainshaft Speed Sensor Circuit |
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. | Clear the DTC in CLEAR MENU with the Honda PGM Tester or HDS. |
| 2. | Check for proper 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) for more than 10 seconds. |
| 5. | Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0716. Did the result fail? YES - Go to 6. NO - Intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETE, return to step 4 and recheck.n |
| 6. | Turn the ignition switch OFF. |
| 7. | Jump the SCS line with the Honda PGM Tester or HDS. |
| 8. | Disconnect PCM connector A (31P) and mainshaft speed sensor connector. |
| 9. | Check for continuity between PCM connector terminals A8 and body ground, and between A9 and body ground. PCM CONNECTOR A (31P)LG2 (BRN/YEL)LG1(BRN/YEL)Wire side of female terminals Is there continuity? YES - Go to 10. NO - Repair open in the wires between PCM connector terminals A8 and ground (G101), between A9 and ground (G101), and repair poor ground (G101).n |
| 10. | Connect PCM connector A (31P). |
| 11. | Turn the ignition switch ON (II). |
| 12. | Measure the voltage between No. 1 terminal of the mainshaft speed sensor connector and body ground. MAINSHAFT SPEED SENSOR CONNECTORWire side of female terminalsVCC1 (YEL/RED) Is there about 5 V? YES - Go to 13. NO - Go to 27. |
| 13. | Turn the ignition switch OFF. |
| 14. | Disconnect PCM connector C (22P). |
| 15. | Check for continuity between the No. 2 terminal of the mainshaft speed sensor connector and body ground. MAINSHAFT SPEED SENSOR CONNECTORWire side of female terminalsNM (WHT/RED) Is there continuity? YES - Repair short to ground in the wire between PCM connector terminal C19 and mainshaft speed sensor connector.n NO - Go to 16. |
| 16. | Check for continuity between the No. 3 terminal of the mainshaft speed sensor connector and body ground. MAINSHAFT SPEED SENSOR CONNECTORWire side of female terminals(BRN/YEL) Is there continuity? YES - Go to 17. NO - Repair open in the wire between the mainshaft speed sensor connector and ground (G101).n |
| 17. | Connect PCM connector C (22P). |
| 18. | Turn the ignition switch ON (II). |
| 19. | Measure the voltage between the No. 2 and No. 3 terminals of the mainshaft speed sensor connector. MAINSHAFT SPEED SENSOR CONNECTORWire side of female terminalsNM (WHT/RED)(BRN/YEL) Is there about 5 V? YES - Go to 20. NO - Go to 32. |
| 20. | Connect the mainshaft speed sensor connector. |
| 21. | Measure the voltage between PCM connector terminals C19 and A8 or A9. PCM CONNECTORSLG1(BRN/YEL)NM (WHT/RED)Wire side of female terminalsA (31P)C (22P)LG2 (BRN/YEL) Is the voltage 0 V or about 5 V? YES - Go to 22. NO - Replace the mainshaft speed sensor. After replacing the sensor, go to 24, and check that the repair has been completed. |
| 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 A8 or A9. PCM CONNECTORSLG1(BRN/YEL)NM (WHT/RED)Wire side of female terminalsA (31P)C (22P)LG2 (BRN/YEL) Is there 1.5 V-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.n NO - Replace the mainshaft speed sensor. After replacing the sensor, go to 24, and check that the repair has been completed. |
| 24. | Clear the DTC in CLEAR MENU with the Honda PGM Tester or HDS. |
| 25. | Test-drive the vehicle for several minutes under the same conditions as those indicated by the freeze data. |
| 26. | Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0716. Did the result pass? YES - The problem has been corrected.n NO - Return to step 1 and recheck.n |
| 27. | Measure the voltage between PCM connector terminals A21 and A8 or A9. PCM CONNECTOR A (31P)LG2 (BRN/YEL)LG1(BRN/YEL)Wire side of female terminalsVCC1 (YEL/RED) Is there 4.75 V-5.25 V? YES - Repair open in the wire between PCM connector terminal A21 and the mainshaft speed sensor connector.n NO - Go to 28. |
| 28. | Turn the ignition switch OFF. |
| 29. | Jump the SCS line with the Honda PGM Tester or HDS. |
| 30. | Disconnect PCM connector A (31P). |
| 31. | Check for continuity between PCM connector terminal A21 and body ground. PCM CONNECTOR A (31P)VCC1 (YEL/RED)Wire side of female terminalsIs there continuity? YES - Repair short to ground in the wire between PCM connector terminal A21 and the mainshaft speed sensor connector.n NO - Check for loose or poor connections at PCM connector terminal A21. If the connections are 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.n |
| 32. | Measure the voltage between PCM connector terminals C19 and A8 or A9. PCM CONNECTORSLG1(BRN/YEL)NM (WHT/RED)Wire side of female terminalsA (31P)C (22P)LG2 (BRN/YEL) Is there about 5 V? YES - Repair open in the wire between PCM connector terminal C19 and the mainshaft speed sensor connector.n NO - Check for loose or poor connections at PCM connector terminal C19. If the connections are 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.n |
