Was bedeutet der Fehlercode?
The engine control module (ECM) keeps watch over the ignition circuitry. The code is set when the signal from ignition coil 2, which feeds cylinders 2 and 3, reads too high. The most common cause is the primary wire touching a supply voltage, but a damaged coil can also trigger the fault.
Mögliche Ursachen
- Primary wire short-circuited to supply voltage
- Damaged ignition coil
Was Sie tun können
- 1Read and clear the code, then road test to see whether it returns
- 2Check that the connector to ignition coil 2 is secure and free from corrosion
- 3Look for a pinched or chafed cable on the primary wire where it may have touched a live conductor
- 4If you have a diagnostic tool: check in live data whether the ignition coil 2 signal reads too high while the engine runs
- 5If the fault remains after these checks, have a workshop decide whether the coil should be replaced
