What P0211 means
P0211 reports an electrical fault, mainly an open circuit, in the injector circuit of cylinder 11. The engine module watches each injector output: GM flags an open circuit at an impedance of 200 kΩ or more – on direct injection and diesel engines in 10 of 20 or 5 of 10 samples and with the warning light in the first trip, on some port-injected engines only after two trips. Ford's port injection reads a fault bit from the driver chip that covers open, short to ground and short to voltage alike; Ford diesels report only the open circuit here and shorts as P0291/P0292. Cylinder 11 exists only on twelve-cylinder engines. No publicly available manufacturer document using this code was found; the description follows the documented codes for cylinders 1–10 and CARB's circuit monitoring requirement.
P0211 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0211
- Check engine light on
- Misfire and rough running, misfire code P0311
- Loss of power, rough idle
- Limp mode possible on diesel and direct injection
Common causes of P0211
- Most likelyConnector at the cylinder 11 injector loose, corroded or with a broken or pushed-back pin
- PossibleInjector coil open
- PossibleWire between module and injector open or chafed (heat, rodents)
- Less likelyInjector supply missing (fuse, relay) – then usually several cylinders at once
- Less likelyDriver stage in the engine module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0211 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2 | Area: fuel and air metering (injector circuit). |
| 11 | The exact fault in that area. |
What to do next
- Note P0211 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0211
What does P0211 mean?
P0211 means "Cylinder 11 Injector A Circuit/Open". P0211 reports an electrical fault, mainly an open circuit, in the injector circuit of cylinder 11. It is a generic code, so it means the same on every make.
Is it safe to drive with P0211?
Drive gently and only to a workshop. With P0211 the car can go into limp mode (reduced power) to protect itself.
Will P0211 fail an emissions test?
Yes, it can. P0211 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0211 to fix?
Difficulty: hard. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0211 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
