W/Harness Inspection

P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input

Inspection/Repair - W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?
YES
1) Repair as necessary and go to "Verification of Vehicle Repair" procedure.
NO
1) Go to "Power Circuit Inspection" procedure.

Power Supply Circuit Inspection
