| DTC P0108: | MAP Sensor Circuit High 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 160 kPa(1,197 mmHg, 47.1 in.Hg), 4.49 V or more 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. | Connect the MAP sensor 3P connector terminals No. 2 and No. 3 with a jumper wire. |
| 6. | Turn the ignition switch ON (II). |
| 7. | Check the MAP SENSOR in the DATA LIST with the Honda PGM Tester or the HDS. Is about 160 kPa(1,197 mmHg, 47.1 in.Hg), 4.49 V or more indicated? YES - Go to 8. NO - Go to 14. |
| 8. | Remove the jumper wire. |
| 9. | Measure voltage between the MAP sensor 3P connector terminal No. 1 and No. 3. Is there about 5 V? YES - Go to 10. NO - Repair open in the wire between the ECM/PCM (A24) and the MAP sensor, then go to 16. |
| 10. | Turn the ignition switch OFF. |
| 11. | Connect ECM/PCM connector terminals A30 and A24 with a jumper wire. |
| 12. | Turn the ignition switch ON (II). |
| 13. | Check the MAP SENSOR in the DATA LIST with the Honda PGM Tester or the HDS. Is about 160 kPa (1,197 mmHg, 47.1 in.Hg), 4.49 V or more indicated? YES - Go to 20. NO - Repair open in the wire between the ECM/PCM (A30) and the MAP sensor, then go to 16.n |
| 14. | Turn the ignition switch OFF. |
| 15. | Replace the MAP sensor. |
| 16. | Turn the ignition switch ON (II). |
| 17. | Do the ECM/PCM RESET in the CLEAR MENU with the Honda PGM Tester or the HDS. |
| 18. | Do the ECM/PCM idle learn procedure. |
| 19. | 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 P0108 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 |
| 20. | Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM. |
| 21. | 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 P0108 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 - If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM.n |
