P0206 Injector Circuit Malfunction - Cylinder 6

P0206 points to an injector circuit malfunction on cylinder 6. The fault is electrical or control-circuit focused, even when the symptom feels like a misfire.

Code status

Needs verification

Not yet verified against SAE J2012_202509 / J2012DA. Treat unverified rows as a lookup aid, not repair authority.

System: Injector
Scope: iso-sae-controlled-p0
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not treat P0206 as a fuel-quality or spark-plug issue first; the named path is the cylinder 6 injector circuit.

Useful checks before replacing parts

Inspect cylinder 6 injector connector condition, terminal tension, wiring continuity, power feed, and control signal.
Compare injector current, resistance, or balance results against known-good cylinders when the vehicle supports it.
Use misfire data and fuel trims to separate injector-circuit failure from fuel delivery or compression problems.
