P0200 — Injector Circuit/Open
Drivable short-term, but fix now to avoid damage.
What P0200 means
This code means the engine computer has detected an electrical fault, usually an open circuit, in one or more of the fuel injector control circuits. Common causes include broken wiring, a bad connector, or a failed injector, and the fix often involves wiring repair or injector replacement. Because it can affect how fuel is delivered to the cylinders, it should be addressed quickly to avoid misfires and converter damage.
Common symptoms
- Check engine light is on, sometimes flashing
- Engine misfires or runs rough
- Noticeable loss of power
- Hard starting or stalling
- Increased fuel consumption or fuel smell
Common causes
- Open or broken injector wiring
- Corroded or loose injector connector
- Failed fuel injector
- Damaged or chafed wiring harness
- Faulty injector driver in the engine control module
Typical repair cost
$150 – $500
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0200 code?
It's best not to. A faulty injector circuit can cause misfires that damage the catalytic converter and lead to stalling, so limit driving and get it diagnosed promptly, especially if the check engine light is flashing.
How much does it cost to fix a P0200 code?
Repairs typically range from $150 to $500. A wiring or connector repair is cheaper, while replacing one or more fuel injectors raises the cost depending on the engine and parts.
Is a P0200 code serious?
Yes, it can be. It affects fuel delivery and can cause misfires, lost power, and converter damage if ignored, so it should be treated as a higher-priority repair.
Does P0200 mean a specific injector is bad?
Not necessarily. P0200 refers to the injector circuit in general, while codes like P0201 through P0208 point to specific cylinders. A technician will test the wiring and injectors to find the exact source.
