P0069 fault code: Manifold Absolute Pressure - Barometric Pressure Correlation

P0069 means “Manifold Absolute Pressure - Barometric Pressure Correlation” — a fuel and air metering fault in the powertrain.

Can I DIY?

Professional-only boundary. Read the code at key-on; do not unplug MAP sensors to 'test' them.

What to tell the garage about P0069

Do not drive. Manifold absolute pressure and barometric (outside) pressure do not agree at a point where the computer expects them to line up, so altitude and load calculations can be wrong from key-on.

What does P0069 mean?

P0069 is a generic (SAE standard) powertrain code reported by your car’s engine control unit. It sits in the P00xx block, which covers fuel and air metering. The stored description is “Manifold Absolute Pressure - Barometric Pressure Correlation”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.

Will P0069 fail an MOT?

If the malfunction indicator lamp is on at MOT, it is a Major fail. Barometric correlation is not listed as its own MOT test.
