P0107 fault code: Manifold Absolute Pressure/Barometric Pressure Circuit Low Input

P0107 means “Manifold Absolute Pressure/Barometric Pressure Circuit Low Input” — a fuel and air metering fault in the powertrain.

Can I DIY?

Professional-only boundary. Confirm P0107; do not pinch or pull MAP pipes as a published test.

What to tell the garage about P0107

Do not drive. Manifold or barometric pressure is reading too low on the circuit — a weak electrical signal, not a finding that the inlet manifold is cracked.

Take these reviewed, code-specific details with you. They help the garage confirm the fault without turning this page into a repair procedure.

  • Manifold Absolute Pressure/Barometric Pressure Circuit Low Input: Registration number
  • Manifold Absolute Pressure/Barometric Pressure Circuit Low Input: Exact code P0107 and freeze-frame if the scanner stored load or rpm
  • Manifold Absolute Pressure/Barometric Pressure Circuit Low Input: Whether the fault is worse at idle or on overrun
  • Manifold Absolute Pressure/Barometric Pressure Circuit Low Input: Any recent inlet-manifold or servo-hose work

What does P0107 mean?

P0107 is a generic (SAE standard) powertrain code reported by your car’s engine control unit. It sits in the P01xx block, which covers fuel and air metering. The stored description is “Manifold Absolute Pressure/Barometric Pressure Circuit Low Input”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.

Will P0107 fail an MOT?

An illuminated engine management light is a Major defect at MOT until repaired and the lamp stays off. P0107 is a low manifold/baro circuit input, not an MOT vacuum test.

Is it safe to drive with P0107?

Do not drive. We have no verified driving guidance for P0107 — treat as do not drive until checked. A low MAP input is not a cue to pinch vacuum pipes to 'prove' the sensor.
