P0293
Cylinder 11 Contribution/Balance
Fuel injectors / cylinder balance
Generic OBD-II
High
What it means
P0293 means cylinder 11 isn't contributing its share of power — the ECM measures uneven crankshaft acceleration between cylinders and flags cylinder 11 as weak. The cause is usually a restricted or weak injector, but low compression or a fuel-delivery problem on that cylinder can also be behind it.

Can I keep driving? Driveable short-term, but cylinder 11 misfiring can damage the converter over time; fix it soon.
Common symptoms
What you'll notice
- Check-engine light on
- Rough idle or vibration

- Hesitation under load
Common causes
Most likely first
- Restricted, weak, or failing cylinder 11 injectorLikely
- Low fuel pressure or a clogged fuel filter starving the cylinderCommon
- Low compression on cylinder 11 (valve or ring wear)Common
- Wiring or connector fault on the cylinder 11 injectorLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame and check for companion misfire or injector codes on cylinder 11.
- Compare injector flow/resistance or perform an injector-balance test.
- Check fuel pressure and filter condition.
- Run a compression test on cylinder 11 if injector and fuel checks are good.
- Repair or replace the weak component, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0293?+
A weak cylinder misfires and can damage the catalytic converter over time. It's driveable short-term, but repair it soon.
Can I just clear P0293?+
It returns once the ECM again detects cylinder 11 underperforming; the underlying weakness has to be repaired.
