P0092 fault code: Fuel Pressure Regulator 1 Control Circuit High
We have no verified driving guidance for P0092 — treat as do not drive until a garage has seen the car. Do not crack fuel pipes or the rail to 'test' pressure.
Can I DIY?
Professional-only boundary. Scan to confirm P0092 only; regulator and rail work is garage-only.
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 P0092
Do not drive. The computer sees too high a voltage on the wire that commands fuel-pressure regulator 1. That is an electrical-control flag. It does not authorise opening a high-pressure fuel rail.
Take these reviewed, code-specific details with you. They help the garage confirm the fault without turning this page into a repair procedure.
- Fuel Pressure Regulator 1 Control Circuit High: Registration number
- Fuel Pressure Regulator 1 Control Circuit High: Exact code P0092 and any companion fuel-pressure or injector codes
- Fuel Pressure Regulator 1 Control Circuit High: Whether the engine management light is steady or flashing
- Fuel Pressure Regulator 1 Control Circuit High: Any fuel smell, wet patches, or recent fuel-filter work
What does P0092 mean?
P0092 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 Pressure Regulator 1 Control Circuit High”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.
Will P0092 fail an MOT?
An illuminated engine management light is a Major defect at MOT until the fault is repaired and the lamp stays off. P0092 is not itself a named MOT inspection item.
