P0206: Injector Circuit / Open - Cylinder 6

P0206 means the engine control unit detected an electrical fault (open circuit, short, or out-of-range resistance) in the wiring or driver for the cylinder 6 fuel injector. It appears on engines with six or more cylinders. The injector itself may be fine while the wiring, connector, or ECU driver is at fault. Left unrepaired it causes a cylinder 6 misfire. Typical repair runs about 60 to 350 EUR depending on whether it is wiring or a replacement injector.

P0206 è un codice diagnostico di guasto relativo a sistema di alimentazione, classificato con gravità moderate. Quando la centralina (ECU) del tuo veicolo rileva questa condizione, memorizza P0206 e accende la spia motore.

Se il tuo veicolo ha attivato P0206, potresti notare uno o più di questi sintomi:

• Check engine light illuminated, often flashing under load
• Rough idle and noticeable misfire
• Hesitation or stumble on acceleration
• Loss of power and reduced fuel economy
• Raw fuel or sulphur smell from the exhaust
• Hard starting when cold

Ecco le cause più comuni di P0206, ordinate in base alla probabilità che siano la causa del problema:

In genere sì, per brevi tragitti. Drivable short-term, but a dead or intermittent cylinder 6 injector causes a misfire that dumps unburnt fuel into the exhaust and can overheat and destroy the catalytic converter. Expect rough running and reduced power. Repair promptly to avoid a much more expensive catalyst replacement.

Segui questi passaggi per individuare la causa principale di P0206:

1. Read the stored code and freeze frame with Skanyx to confirm it is P0206 and note the conditions (RPM, load, coolant temp) when it set
2. Check for a companion P0300 random misfire code, which points to a genuine combustion problem on the affected cylinder
3. Inspect the cylinder 6 injector connector and harness for corrosion, looseness, melted pins, or chafing
4. With the engine off, measure the injector winding resistance with a multimeter and compare against the workshop spec (most petrol injectors read roughly 12-17 ohms)
5. Check for the injector control and supply circuits with a multimeter or test light, and swap the suspect injector to another cylinder to see if the fault follows it
6. Note that per-injector coding, flow balance, and quantity-correction values are not on generic OBD2 - read those with a brand tool such as Carly, OBDeleven, or XENTRY, or have a workshop verify them
