P0292
ModerateCylinder 11 Injector Circuit High
Eleven firing cylinders will keep the car feeling composed, but the unburned fuel from cylinder 11 quietly stresses that bank's catalytic converter with every mile. Arrange the repair promptly regardless of how the engine feels, and park the car if the light flashes.
What this code means
The high-side counterpart to P0291, this code sets when the ECM finds voltage above the expected range on the cylinder 11 injector control circuit — and like its sibling, it can only occur on engines with eleven-plus cylinders, effectively V12s. Typical high-side causes are a short to battery voltage in the harness or resistance added by corrosion at the connector, a deteriorated terminal, or an injector winding that has failed open. The monitor evaluates electrical behavior only, which cleanly separates this from a clogged injector: deposits block fuel mechanically and would produce a misfire code without a circuit code. Diagnosis on a V12 leans on its abundance of identical circuits — compare cylinder 11's injector resistance and connector condition to any healthy neighbor. Expect P0211 (circuit) and P0311 (misfire) as related codes. Verify which physical cylinder is number 11 on your engine, as twelve-cylinder numbering conventions vary by manufacturer.
Symptoms you might notice
- Cylinder 11 misfire, usually masked by the remaining eleven cylinders
- Subtle loss of smoothness or a faint tick in the exhaust note
- Marginal power and economy reduction
- Check-engine light; flashing means active misfire
- Often stored with no felt symptoms when the fault is intermittent
What it costs to fix
Typical range: $60–$450 · about ~0.5–2 hrs of labor
| If the cause is… | Part | Labor |
|---|---|---|
| Fuel injector (single) | $50–$300 | ~0.5–2 hrs |
| Wiring/connector repair | $5–$50 | ~0.5–2 hrs |
On V12s the labor dwarfs the parts for anything buried under the intake, and direct-injection injectors for these engines are premium items — plan for the top of the range unless the fault turns out to be an accessible connector.

Frequently asked
What separates P0292 from P0291?
Only the direction of the voltage fault on the same cylinder 11 circuit. P0292 means the voltage ran high — open circuit, corrosion resistance, or a short to battery voltage. P0291 means it ran low — short to ground or shorted injector coil.
Could this just be a dirty connector?
Quite possibly. Corroded or fretted connector pins are a leading cause of circuit-high codes, and on a V12 the connector is far cheaper to service than anything requiring intake removal. Inspect and clean the cylinder 11 connector before committing to bigger jobs.
Why is it intermittent on my car?
Marginal connections respond to heat, humidity, and vibration — conducting normally most of the time and faulting occasionally. That pattern points strongly at the connector or a chafed harness section rather than a cleanly failed injector, which tends to fault consistently.
Can I drive with P0292 while awaiting parts?
Gentle, limited driving with a steady light is generally acceptable. The risk isn't breakdown — it's cumulative catalytic converter damage from unburned fuel, and V12 exhaust systems are extremely costly. A flashing check-engine light means stop driving until repaired.
