Was bedeutet der Fehlercode?
The ECM tests whether the fuel injectors shut off properly when the engine stops. During shut-down the engine speed should fall as expected. If the ECM registers a faulty signal from the injector output stage, the code is set. A leak in the fuel system is one possible cause, but a defective pressure control valve, relief valve, injector or fuel pressure sensor can also set it.
