P0262 Fault Code: What It Means and What To Do

What does P0262 mean?

P0262 is logged when your car's control module detects: Cylinder 1 Injector Circuit High. It's classed as a fuel system fault.

P (powertrain) codes relate to the engine, gearbox and emissions systems. The P0 prefix means it's a generic code, so it means the same thing on every make of car.

The fuel system delivers and meters the fuel your engine burns — the pump, injectors, pressure regulator and the oxygen sensors that let the engine computer fine-tune the mixture. Faults here can cause hesitation, stalling, rough idle, poor economy or a fuel smell.

Is it safe to drive with P0262?

Only for short, essential journeys. This kind of fault can get worse or cause knock-on damage, so book the car in as soon as you can. If the engine light is flashing, the car feels noticeably wrong, or you smell fuel or burning, stop driving.

This is a general rating for the code. The real risk depends on your car and the symptoms you're getting — a tailored explanation will take your make, model, engine and MOT history into account.

What to do next

• Note any symptoms — when the light came on, and whether the car feels, sounds or smells different. It helps a garage narrow down the cause quickly.
• Check for other codes — faults often log several related codes at once, and the first one is usually closest to the root cause.
• Don't just clear it — the code will usually come back if the fault is still there, and clearing it wipes the freeze-frame data a garage uses to diagnose it.
• Get it diagnosed — a garage diagnostic check typically costs £50–£100 in the UK, and is often deducted from the repair if you go ahead with them.

A dashboard warning light that stays on — such as the engine management or ABS light — is an MOT failure, so get it fixed before your next test.
