Drive with caution — fix soon.
This code means the engine computer detected an electrical fault in the cold start injector circuit, the injector that delivers extra fuel to help a cold engine start. It usually points to a faulty cold start injector, damaged wiring or connectors, or a problem in its control circuit. Repairs typically involve testing and replacing the injector or fixing the wiring, and it's usually a straightforward fix.
$150 – $450
Varies by vehicle and root cause.
Usually yes, since this mainly affects cold starting rather than driving once the engine is warm. Still, have it checked before cold weather and watch for any fuel smell, which can mean a stuck-open injector that floods the engine.
Most repairs land between $150 and $450. A wiring or connector fix is on the lower end, while replacing the cold start injector with labor sits at the higher end.
It's usually moderate. The main symptom is hard cold starting, which is annoying but not dangerous. The exception is a stuck-open injector that floods the engine, so it's worth fixing rather than leaving indefinitely.
It sprays extra fuel during a cold start so the engine catches quickly when it's hard to ignite. Once the engine warms up it stops being needed, which is why a fault here mostly shows up first thing on cold mornings.
