Drive with caution — fix soon.
This code means the engine computer detected low voltage in the electrical circuit for the cylinder 7 fuel injector. It usually points to a wiring problem, a corroded connector, or a failing injector on that cylinder. It's a circuit-level fault that's typically fixable by repairing wiring or replacing the injector, without major engine work.
$120 – $600
Varies by vehicle and root cause.
Usually yes for short trips, but don't ignore it. The affected cylinder may not be fueling correctly, which causes rough running and can harm the catalytic converter over time. Get it diagnosed soon.
A wiring or connector repair can be as low as $120, while replacing the cylinder 7 injector typically runs $300 to $600 depending on the vehicle. A proper diagnosis pins down which it is.
It's moderate. The car will often still run, but a misfueling cylinder means lost performance and possible converter damage if left alone. It's worth fixing promptly but rarely an emergency.
It means the computer sent a command to the cylinder 7 injector but measured lower-than-expected voltage in that circuit. That usually points to a wiring fault, a bad connector, or an injector that isn't responding properly.
