P0292
Cylinder 11 Injector A Circuit High
Fuel injector circuit
Generic OBD-II
High
What it means
P0292 means the ECM detected a high-voltage condition — typically an open circuit or short-to-voltage — in the electrical circuit that fires cylinder 11's fuel injector. When that injector can't pulse correctly, cylinder 11 runs weak or dead, causing a rough-running misfire. It's primarily an electrical fault in the injector wiring, connector, or the injector itself.
High
Can I keep driving? Drivable but not advisable — a dead or weak cylinder 11 injector causes a misfire that can overheat and damage the catalytic converter.
Common symptoms
What you'll notice
- Check-engine light on (may flash if cylinder 11 is misfiring)
- Rough idle and engine shake
- Misfire, hesitation, or stumble from a weak/dead cylinder 11
- Reduced power and higher fuel consumption
Common causes
Most likely first
- Open circuit or short-to-voltage (high signal) in the cylinder 11 injector wiringLikely
- Damaged, corroded, or loose connector at the cylinder 11 injectorCommon
- Failed injector coil/winding on cylinder 11Common
- Faulty injector driver in the engine control module (ECM) — least commonLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and confirm the fault is isolated to cylinder 11.
- Inspect the cylinder 11 injector connector and wiring for opens, a short to voltage, corrosion, or damage.
- Measure the injector's resistance and compare to the other injectors and to spec.
- Swap or replace the injector if out of range; if wiring and injector are good, have the ECM driver checked. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0292?+
Not for long. A misfiring cylinder dumps unburned fuel into the exhaust and can quickly damage the catalytic converter, so repair it soon.
Can I just clear P0292?+
It clears, but an injector-circuit fault returns until the wiring, connector, or injector is repaired.
