P0107: Manifold Absolute Pressure/Barometric Pressure Sensor Circuit Low

Fix soon

Usually safe to drive gently to a workshop, but fuel use and running can suffer. Have it checked soon.

What P0107 means

The engine computer is getting a reading from the manifold absolute pressure sensor that is missing, out of range or doesn't make sense. The manifold absolute pressure sensor measures pressure (vacuum or boost) in the intake.

Common causes

  • Split or disconnected vacuum hose to the sensor
  • Faulty MAP sensor
  • Damaged wiring or connector

What to check first

  1. Scan the car to confirm the code and see if others are stored with it.
  2. Check the sensor plug and wiring for corrosion, damage or a loose connection.
  3. Compare the live sensor reading with a known-good value before replacing the part.
