Drivable short-term, but fix now to avoid damage.
This code means your car's computer detected an electrical problem in the wiring or control circuit for the fuel injector on cylinder 7. It usually points to a bad injector, damaged wiring or connectors, or a fault in the circuit that controls it. Repairs typically involve testing and replacing the injector or fixing the wiring, and it's often fixable without major engine work.
$150 – $500
Varies by vehicle and root cause.
For short trips usually yes, but you shouldn't rely on it. A misfiring cylinder can damage your catalytic converter and leave you stranded, so get it checked soon. If the engine is shaking hard or losing power, stop driving and have it towed.
Most repairs fall between $150 and $500. If it's just wiring or a connector the cost is lower, but replacing the fuel injector for cylinder 7 plus labor pushes it toward the higher end.
It can be. A faulty injector circuit often causes misfires that, if ignored, can damage your catalytic converter and hurt fuel economy. It's worth fixing promptly rather than letting it linger.
Each injector has its own circuit, and the computer monitors them individually. The number simply tells your mechanic exactly which injector and wiring to inspect first, which speeds up diagnosis.
