Drive with caution — fix soon.
This code means the computer detected an abnormally low voltage in the circuit that controls cylinder 5's fuel injector. It usually points to a short to ground, a wiring or connector fault, or a failing injector. It's commonly fixable by repairing the circuit or replacing the injector, without major engine work.
$120 – $450
Varies by vehicle and root cause.
For short trips, usually yes, but you shouldn't rely on it. The affected cylinder may not fire properly, causing rough running and lost power. Have it checked soon to avoid converter or engine damage.
Repairs typically range from about $120 to $450. A wiring or connector repair is on the cheaper end, while replacing the injector and diagnostic labor cost more.
It's a moderate concern. The engine usually still runs, but a misfiring cylinder hurts performance and fuel economy. It's best to address it before it gets worse.
It means the computer sees too little voltage in the injector control circuit, often from a short to ground or a faulty injector. The injector may not be opening properly, so that cylinder doesn't get the right amount of fuel.
