The VCC1 wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P0107 goes away and the PCM was updated, troubleshooting is complete. If DTC P0107 goes away and the PCM was substituted, replace the original PCM.?
NO
Repair an open in the VCC1 wire between the PCM (C41) and the MAP sensor.?

Is there continuity?
YES
Repair a short in the PB wire between the PCM (C45) and the MAP sensor.?
NO
The PB wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P0107 goes away and the PCM was updated, troubleshooting is complete. If DTC P0107 goes away and the PCM was substituted, replace the original PCM.?
