Drive with caution — fix soon.
This code means the engine computer detected an abnormally high voltage in the wiring or control circuit for the fuel injector on cylinder 11. It usually points to a wiring problem, a bad connector, or a failing injector rather than a major engine fault. Typical fixes include repairing damaged wiring, cleaning or replacing the injector connector, or replacing the injector itself.
$150 – $500
Varies by vehicle and root cause.
For short trips, usually yes, but you shouldn't rely on it. The affected cylinder may run poorly and could lead to a misfire that damages your catalytic converter. Get it checked soon, and if the light starts flashing, stop driving.
Most repairs run between $150 and $500. A simple wiring or connector fix is on the low end, while replacing the injector on cylinder 11 costs more, especially on large V10 or V12 engines.
It's moderate. The car will usually still run, but ignoring it can lead to misfires and converter damage. It's worth addressing promptly rather than letting it linger.
Cylinder 11 only exists on large engines with 10 or 12 cylinders, like some luxury and high-performance vehicles. If you see this code, your engine has a high cylinder count and the fault is specific to that injector circuit.
