P0211 — Injector Circuit Malfunction - Cylinder 10
Drivable short-term, but fix now to avoid damage.
What P0211 means
This code means the engine computer detected an electrical problem in the wiring or control circuit for the fuel injector on cylinder 10, found on large V10 and V12 engines. The common causes are a faulty injector, damaged wiring or connectors, or a fault in the circuit that controls it. Repair usually involves testing the injector and wiring and replacing the failed component, and it's often fixable without major engine work.
Common symptoms
- Check engine light is on
- Rough idle or noticeable engine shaking
- Engine misfires or hesitates under load
- Loss of power or poor acceleration
- Increased fuel consumption or rough running
Common causes
- Faulty fuel injector on cylinder 10
- Damaged or corroded injector wiring or connector
- Open or short circuit in the injector control wiring
- Failed injector driver in the engine control module
- Poor electrical ground or loose connection
Typical repair cost
$150 – $550
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0211 code?
Short trips are usually okay, but don't rely on it. A misfiring cylinder can damage your catalytic converter and may leave you stranded, so get it checked soon. If it's shaking badly or low on power, stop and have it towed.
How much does it cost to fix a P0211 code?
Typically $150 to $550. Wiring or connector fixes sit at the lower end, while replacing an injector on a big V10 or V12 engine with labor moves it toward the top of the range.
Is a P0211 code serious?
It can be. This injector fault usually triggers misfires that, if ignored, can harm your catalytic converter and reduce fuel economy. Addressing it promptly is the smart move.
Could one bad injector really affect the whole engine?
Yes. Even one underperforming cylinder makes the engine run unevenly, which you feel as shaking and lost power, and it forces the other cylinders to work harder. Fixing cylinder 10 restores smooth, balanced running.
