| DTC P0107: | MAP Sensor Circuit Low Voltage |
| 1. | Turn the ignition switch ON (II). |
| 2. | Check the MAP SENSOR in the DATA LIST with the Honda PGM Tester or the HDS. Is about 3 kPa (26 mmHg, 1.0 in.Hg), or 0.23 V or less indicated? YES - Go to 3. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the MAP sensor and the ECM/PCM.n |
| 3. | Turn the ignition switch OFF. |
| 4. | Disconnect the MAP sensor 3P connector. |
| 5. | Turn the ignition switch ON (II). |
| 6. | Check the MAP SENSOR in the DATA LIST with the Honda PGM Tester or the HDS. Is about 3 kPa (26 mmHg, 1.0 in.Hg), or 0.23 V or less indicated? YES - Go to 9. NO - Go to 7. |
| 7. | Measure voltage between MAP sensor 3P connector terminal No. 1 and No. 3. Is there about 5 V? YES - Go to 13. NO - Go to 8. |
| 8. | Measure voltage between ECM/PCM connector terminals A21 and A24. Is there about 5 V? YES - Repair open in the wire between the ECM/PCM (A21) and the MAP sensor, then go to 15. NO - Go to 19. |
| 9. | Turn the ignition switch OFF. |
| 10. | jump the SCS line with the Honda PGM Tester or the HDS. |
| 11. | Disconnect ECM/PCM connector A (31P). |
| 12. | Check for continuity between MAP sensor 3P connector terminal No. 2 and body ground. Is there continuity? YES - Repair short in the wire between the ECM/PCM (A30) and the MAP sensor, then go to 15. NO - Go to 19. |
| 13. | Turn the ignition switch OFF. |
| 14. | Replace the MAP sensor. |
| 15. | Turn the ignition switch ON (II). |
| 16. | Do the ECM/PCM RESET in the CLEAR MENU with the Honda PGM Tester or the HDS. |
| 17. | Do the ECM/PCM idle learn procedure. |
| 18. | Check for Temporary DTCs or DTCs in the DTCs MENU with the Honda PGM Tester or the HDS. Are any Temporary DTCs or DTCs indicated? YES - If DTC P0107 is indicated, check for poor connections or loose terminals at the MAP sensor and the ECM/PCM, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC troubleshooting. NO - Troubleshooting is complete.n |
| 19. | Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM. |
| 20. | Check for Temporary DTCs or DTCs in the DTCs MENU with the Honda PGM Tester or the HDS. Are any Temporary DTCs or DTCs indicated? YES - If DTC P0107 is indicated, check for poor connections or loose terminals at the MAP sensor and the ECM/PCM, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC troubleshooting. |
