Drivable short-term, but fix now to avoid damage.
This code means cylinder 7 is producing less power than the other cylinders, so the engine computer flags it as out of balance. It usually points to a weak or clogged fuel injector, low compression, or an ignition fault on that cylinder. It's a common code on multi-cylinder engines, and once the cause is found it's often fixable without tearing into the engine.
$150 – $900
Varies by vehicle and root cause.
For short trips, usually yes, but you shouldn't depend on it. The engine is unbalanced, which can worsen and damage other parts. If the light is flashing or the car shakes badly, stop driving and get help right away.
It varies with the cause. An injector or ignition coil replacement often runs $150 to $500, while compression repairs can reach $900 or more. Diagnosis comes first so you only pay for what's needed.
It's fairly serious. A cylinder not pulling its weight means lost power and potential misfiring that can damage the catalytic converter over time. Address it promptly.
The computer measures how much each cylinder contributes to engine rotation. When cylinder 7 lags behind the rest, it flags that specific cylinder. The repair focuses on why that one is weak, usually fuel, compression, or ignition.
