Was bedeutet der Fehlercode?

Here the signal to the injectors in bank 2 is too high when the engine control module checks it. This can be caused by a short to supply voltage in the wiring, by damaged injectors, or by an internal fault in the module, including a short to supply voltage inside it.

Mögliche Ursachen

Short to supply voltage in the wiring to the injectors
Damaged injectors
Short to supply voltage inside the engine control module (ECM)
Internal fault inside the ECM

Was Sie tun können

1Check that the fuses are intact.
2Check that the connectors at the injectors in bank 2 are secure and not corroded.
3Look for chafed wires or pinch damage on the wiring to the injectors in bank 2, where they could have touched supply voltage.
4Have a workshop measure whether the wiring has contact with voltage, as the measurement is made with the ignition on.
5If the wiring is undamaged, have a workshop check the injectors in bank 2 and the control module with diagnostic equipment.
