P0206

Cylinder 6 Injector A Circuit

Q: 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.

Q: Can I just clear P0206?

It returns quickly if the injector or its wiring is faulty — the circuit fault has to be repaired.

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.

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.
