P0006 fault code: Fuel Shutoff Valve 'A' Control Circuit Low

P0006 means “Fuel Shutoff Valve 'A' Control Circuit Low” — a fuel and air metering fault in the powertrain.

Can I DIY?

Professional-only boundary. Do not apply battery voltage to shut-off valve A to 'see it click'.

What to tell the garage about P0006

Do not drive until checked. Fuel shut-off valve A’s control circuit is sitting low. The computer sees too little voltage or current on that valve’s command wire, not an open-circuit P0005.

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

What does P0006 mean?

P0006 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 “Fuel Shutoff Valve 'A' Control Circuit Low”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.

Will P0006 fail an MOT?

DVSA MOT inspection treats a lit engine management light as Major. P0006 is a low-circuit result on shut-off valve A, not an exhaust emissions figure.
