P0107
DTC P0107: MAP Sensor Circuit Low Voltage1. 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 terminals at the MAP sensor and at the PCM.
NO - Go to step 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 step 8.
NO - Go to step 7.
7. Measure voltage between PCM connector terminals C19 and C7.
Is there about 5 V ?
YES - Repair open in the wire between the PCM (C19) and the MAP sensor.
NO - Substitute a known-good PCM and recheck. If normal MAP is indicated, replace the original PCM.
8. Check the MAP with the scan tool.
Is about 2 kPa (15 mmHg, 0.6 in.Hg) or less, or 0 V indicated?
YES - Go to step 9.
NO - Replace the MAP sensor.
9. Turn the ignition switch OFF.
10. Disconnect PCM connector C (31P).
11. 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 PCM (C17) and the MAP sensor.
NO - Substitute a known-good PCM and recheck. If normal MAP is indicated, replace the original PCM.
