Drive with caution — fix soon.
This code means the engine computer detected a problem in the circuit or operation of the second cold start injector, which sprays extra fuel to help the engine start when it's cold. It's often caused by a bad injector, wiring or connector issues, or a faulty temperature sensor signal. Repairs usually involve testing the circuit and replacing the injector or fixing the wiring.
$120 – $400
Varies by vehicle and root cause.
Usually yes, especially once the engine is warm, but you may have trouble starting on cold mornings. It's best to get it checked soon so a cold start doesn't leave you stranded.
Repairs typically run between $120 and $400, depending on whether it's a wiring fix or a full injector replacement. Diagnosis time and your vehicle's design affect the final price.
It's a moderate issue. Your car will usually still run, but ignoring it can lead to frustrating cold-start problems and extra fuel use, so it's worth fixing.
The cold start injector mainly adds fuel during a cold start. When the engine is already warm it isn't needed, so a fault often shows up only on cold mornings.
