| DTC P0107(3-1): | MAP Sensor Circuit Low Voltage |
| 1. | Turn the ignition switch ON (II). |
| 2. | Check the MAP with the scan tool. Is about 101 kPa (760 mmHg, 30 in.Hg) or 2.9 V indicated? YES - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the MAP sensor and at the ECM/ PCM.n NO - Go to 3. |
| 3. | Turn the ignition switch OFF. |
| 4. | Disconnect the MAP sensor 3P connector. |
| 5. | Turn the ignition switch ON (II). |
| 6. | Measure voltage between the MAP sensor 3P connector terminals No. 1 and No. 3.
Is there about 5 V? YES - Go to 8. NO - Go to 7. |
| 7. | Measure voltage between ECM/PCM connector terminals A11 and A21.
Is there about 5 V? YES - Repair open in the wire between ECM/PCM (A21) and the MAP sensor.n NO - Substitute a known-good ECM/PCM and recheck. If the symptom/indication goes away, replace the original ECM/ PCM.n |
| 8. | Check the MAP with the scan tool. Is 2 kPa (15 mmHg, 0.6 in.Hg) or less or 0 V indicated? YES - Go to 9. NO - Replace the MAP sensor.n |
| 9. | Turn the ignition switch OFF. |
| 10. | Disconnect the negative cable from the battery. |
| 11. | Disconnect ECM/PCM connector A (31P). |
| 12. | Check for continuity between the MAP sensor connector terminal No. 2 and body ground.
Is there continuity? YES - Repair short in the wire between the ECM/PCM (A19) and the MAP sensor.n NO - Substitute a known-good ECM/PCM and recheck. If the symptom/indication goes away, replace the original ECM/ PCM.n |
