P0206
Cylinder 6 Injector A Circuit
Fuel injector circuit
Generic OBD-II
High
What it means
P0206 means the ECM has detected an electrical fault in the fuel injector circuit for cylinder 6 — an open, short, or out-of-range resistance. If the injector isn't being driven, cylinder 6 gets no fuel and misfires, so the engine runs rough and loses power. It usually still runs on the remaining cylinders.
High
Can I keep driving? Limited — cylinder 6 may not be firing, so the engine runs rough and misfires; drive as little as possible to avoid fuel washing the cylinder and damaging the catalytic converter.
Common symptoms
What you'll notice
- Check-engine light on (may flash during a misfire)
- Rough idle and a noticeable misfire
- Reduced power and hesitation
- Increased fuel consumption or a fuel smell
Common causes
Most likely first
- Open or shorted injector wiring to cylinder 6Likely
- Corroded or loose injector connectorCommon
- Failed cylinder 6 fuel injector (open or shorted coil)Common
- Fault in the ECM's injector driverLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame and confirm the fault is on the cylinder 6 injector circuit.
- Measure the injector's coil resistance and compare it to the other injectors.
- Inspect the injector connector and wiring for damage, corrosion, or an open.
- Swap the suspect injector with a neighbouring cylinder to see if the fault follows it.
- Repair the wiring or replace the injector; clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0206?+
Not for long. A dead cylinder makes the engine misfire, and unburned fuel can overheat and damage the catalytic converter. Get it fixed promptly.
Can I just clear P0206?+
It returns quickly if the injector or its wiring is faulty — the circuit fault has to be repaired.
