Was bedeutet der Fehlercode?
This code is a consequential fault of an underlying adaptation code for bank 1. It is set when such a code has been stored in two consecutive driving cycles, and it is always set together with one of them. Although the code is named for a signal that is too low, the root fault is the one to fix first.
