Hva betyr feilkoden?

The signal to the cylinder 6 ignition coil is stored as intermittent. This means the fault may have happened before and is not active at the moment. The code is set when the wire to the coil is shorted to ground or has an open circuit while the engine runs at higher speeds, and the engine then misfires.

Mulige årsaker

Signal wire shorted to ground
Open circuit in the signal wire
Signal wire shorted to supply voltage
Contact resistance in the connections
