Drive with caution — fix soon.
This code means the engine computer measured that cylinder 11 is contributing less power than the other cylinders, throwing off the engine's balance. It often points to a clogged or weak fuel injector, low compression, or a fuel delivery issue on that cylinder. Typical fixes include cleaning or replacing the injector, checking compression, and inspecting the fuel and ignition components for that cylinder.
$150 – $600
Varies by vehicle and root cause.
Short trips are usually fine, but don't ignore it. The unbalanced cylinder can worsen into a misfire and damage your catalytic converter. Get it diagnosed soon, and stop driving if the light starts flashing.
Repairs typically range from $150 to $600. Cleaning or replacing the injector is common, but if low compression is the cause, the cost can climb depending on the underlying engine repair needed.
It's moderate. The engine still runs but isn't performing evenly, which can lead to bigger problems if left alone. It's best to address it before it turns into a full misfire.
It means the computer detected that cylinder 11 produces less power than its neighbors during combustion. This usually traces back to fuel delivery or compression on that specific cylinder rather than the whole engine.
