Was bedeutet der Fehlercode?

The code applies to injector 2 and is set when the engine control module detects a fault on the wiring to the injector while the engine runs. The module drives each injector through its own power stage, where the voltage is above battery voltage. The fault may lie in the injector, the wiring or the control module.

Mögliche Ursachen

Open circuit in the signal or ground wire to the injector
Signal wire short-circuited to ground
Signal or ground wire short-circuited to supply voltage
Defective injector
Defective charging system
Defective engine control module (ECM)

1Read and clear the code, then road test to see whether it returns
2Check that the connector to injector 2 is secure and free from contact resistance and oxidation
3Use a multimeter to check the wires to injector 2 for breaks or shorts to ground or supply voltage
4Have a workshop measure the resistance of the injector
5If the fault remains, have a workshop decide whether the injector or the engine control module is defective
