P0293 — Cylinder 11 Injector Circuit High
Drive with caution — fix soon.
What P0293 means
This code means the engine computer detected an abnormally high voltage in the wiring or control circuit for the fuel injector on cylinder 11. It usually points to a wiring problem, a bad connector, or a failing injector rather than a major engine fault. Typical fixes include repairing damaged wiring, cleaning or replacing the injector connector, or replacing the injector itself.
Common symptoms

- Engine may misfire under load
Common causes
- Faulty fuel injector on cylinder 11
- Damaged or corroded injector wiring
- Loose or corroded injector connector
- Open or short in the injector control circuit
- Failing engine control module (rare)
Typical repair cost

Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0293 code?
For short trips, usually yes, but you shouldn't rely on it. The affected cylinder may run poorly and could lead to a misfire that damages your catalytic converter. Get it checked soon, and if the light starts flashing, stop driving.
How much does it cost to fix a P0293 code?
Most repairs run between $150 and $500. A simple wiring or connector fix is on the low end, while replacing the injector on cylinder 11 costs more, especially on large V10 or V12 engines.
Is a P0293 code serious?
It's moderate. The car will usually still run, but ignoring it can lead to misfires and converter damage. It's worth addressing promptly rather than letting it linger.
Why does my car have a cylinder 11 if most engines don't?
Cylinder 11 only exists on large engines with 10 or 12 cylinders, like some luxury and high-performance vehicles. If you see this code, your engine has a high cylinder count and the fault is specific to that injector circuit.
