P0295 — Cylinder 12 Injector Circuit Low
Drive with caution — fix soon.
What P0295 means
This code means the engine computer detected abnormally low voltage in the wiring or control circuit for the fuel injector on cylinder 12. It typically indicates a short to ground, damaged wiring, a bad connector, or a failing injector. Common fixes include repairing the wiring or connector, or replacing the injector on cylinder 12.
Common symptoms
- Check engine light is on
- Rough idle or engine shaking
- Reduced power or hesitation
- Engine misfire, especially under load
- Increased fuel consumption
Common causes
- Short to ground in the injector wiring
- Faulty fuel injector on cylinder 12
- Damaged or chafed injector harness
- Corroded or loose injector connector
- Failing engine control module (rare)
Typical repair cost
$150 – $500
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0295 code?
Briefly, usually yes, but it's risky. A misfiring cylinder 12 can damage the catalytic converter and leave you stranded. Get it diagnosed soon, and stop driving if the engine shakes hard or the light flashes.
How much does it cost to fix a P0295 code?
Expect $150 to $500 in most cases. Fixing a wiring short or connector is cheaper, while replacing the cylinder 12 injector costs more, particularly on large V12 engines where access can be tight.
Is a P0295 code serious?
It's moderate. The car will usually run, but a poorly firing cylinder can cause misfires and converter damage over time. Address it promptly to avoid bigger repair bills.
What does 'circuit low' mean in this code?
'Circuit low' means the computer saw lower voltage than expected on the injector's control wire, often from a short to ground or a wiring fault. It points to an electrical problem rather than the fuel itself.
