Drivable short-term, but fix now to avoid damage.
This code means the engine computer detected a low-voltage condition in the circuit that controls the fuel injector for cylinder 11. It usually points to a short to ground, damaged wiring, a bad connector, or a failing injector. It's a fairly common circuit fault and is often fixable by repairing the wiring or replacing a single injector without major engine work.
$150 – $500
Varies by vehicle and root cause.
For short trips, usually yes, but don't rely on it. A misfiring cylinder can push unburned fuel into the catalytic converter and cause costly damage, so get it diagnosed soon.
Most repairs land between $150 and $500. A simple wiring or connector fix is cheaper, while replacing the cylinder 11 injector and diagnostic time costs more.
It's on the more serious side because it affects how a cylinder fires. It won't usually strand you right away, but ignoring it can lead to converter damage and worse running.
Each injector has its own monitored circuit, so the computer can identify that the low-voltage fault is on cylinder 11. You'll typically only see this on large V12 engines that have eleven or more cylinders.
