P0002 fault code: Fuel Volume Regulator Control Circuit Range/Performance

P0002 means “Fuel Volume Regulator Control Circuit Range/Performance” — a fuel and air metering fault in the powertrain.

Can I DIY?

Professional-only boundary. You cannot verify regulator performance on the driveway; book a garage.

What to tell the garage about P0002

Do not drive until checked. The volume-regulator command is present, but the response sits outside the band the computer expects. Fuel quantity is not tracking the requested performance.

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 P0002 mean?

P0002 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 Volume Regulator Control Circuit Range/Performance”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.

Will P0002 fail an MOT?

If the engine management light is on, MOT records a Major defect until the lamp stays off. P0002 reports regulator range/performance, not a vapour-leak or catalyst test.
