P0106 fault code: Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance
Driveability guidance is not available for P0106 — treat as do not drive until checked. A false manifold-pressure reading can make the engine hesitate or stall; if it does, or the light flashes, stop and arrange recovery.
Can I DIY?
Professional-only boundary. You may confirm P0106 on a scanner; do not replace the MAP sensor or open the intake.
This is the conservative boundary from the reviewed code record. This page has no frozen site-wide safety grade, so it does not publish a repair route.
What to tell the garage about P0106
Stop driving now. The computer reports the intake-manifold or barometric-pressure signal is outside the range it expects, so fuelling may be wrong. We have no verified drive rating for P0106 — do not assume it is safe to keep driving.
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 Range/Performance: Registration number
- Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance: Exact code P0106 and any companion codes
- Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance: Whether the engine management light is steady or flashing
- Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance: Freeze-frame manifold-pressure or baro reading if the scanner showed one
- Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance: Whether the engine hesitates, stalls, or feels down on power
Never open a hot coolant cap — pressure can scald you. Exhaust and catalytic converter get hot enough to burn and ignite debris. Stay clear of electric fans; they can run after shut-off.
Never idle in a closed garage to read codes — an open door is not enough. CO is odourless and can kill. Run diagnostics in open air. Headache or nausea with exhaust smell: get fresh air and stop.
What does P0106 mean?
P0106 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 Range/Performance”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.
Will P0106 fail an MOT?
If the engine management light is on with P0106 stored, that illuminated lamp is a Major defect at MOT (automatic fail) until the fault is repaired and the light stays off.
