P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input - Inspection/Repair:_:W/Harness Inspection

Terminal & 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?






Power Circuit Inspection

Check Open or Short in power circuit
1. IG KEY "OFF".
2. Disconnect MAPS connector.
3. IG KEY "ON" & ENG "OFF".
4. Measure the voltage between power terminal of MAPS harness connector and chassis ground.

Specification :Approx 5V








5. Is the measured voltage within specification ?






Signal Circuit Inspection

Check Short in signal circuit
1. IG KEY "OFF".
2. Disconnect MAPS connector.
3. IG KEY "ON" & ENG "OFF".
4. Measure the voltage between signal terminal of MAPS harness connector and chassis ground.

Specification :Approx 5V








5. Is the measured voltage within specification ?
