Co oznacza ten kod błędu?
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.
Możliwe przyczyny
- Signal wire shorted to ground
- Open circuit in the signal wire
- Signal wire shorted to supply voltage
- Contact resistance in the connections

- 3Follow the wire to the cylinder 6 coil and look for broken, pinched or chafed sections
