DTC P0107: MAP Sensor Circuit Low Voltage1. Turn the ignition switch ON (II).
2. Check the MAP with a scan tool or the HDS.
Is approx. 101 kPa (760 mmHg, 30 in.Hg), 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 ECM.
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 MAP sensor 3P connector terminals No. 1 and No. 2.
Is there about 5 V?
YES - Go to step 7.
NO - Repair open in the wire between the ECM (C19) and the MAP sensor.
7. Check the MAP with a scan tool or the HDS.
Is approx. 2 kPa (15 mmHg, 0.6 in.Hg), 0.5 V or less Indicated?
YES - Go to step 8.
NO - Replace the MAP sensor.
8. Turn the ignition switch OFF.
9. Disconnect the ECM connector C (31P).
10. Check for continuity between MAP sensor connector terminal No. 3 and body ground.
