Hva betyr feilkoden?
The engine control module (ECM) keeps watch over the ignition circuitry. The code is set when the signal from ignition coil 2 is too low. That coil supplies cylinders 2 and 3. The usual cause is a primary wire shorted to ground or a damaged coil.
Mulige årsaker
- Primary wire shorted to ground
- Damaged ignition coil

- 3Inspect the primary wire to ignition coil 2 for chafing or breaks, especially where it rests against edges in the engine bay
- 4If you have a diagnostic tool: read the ignition coil 2 signal in live data while the engine runs
