Hva betyr feilkoden?

The oxygen sensor on bank 2 is controlled by the engine control module (ECM), and an internal fault has occurred there. The code concerns a signal that is too low, but the fault lies in the control module. If the fault returns despite checks, the control module needs replacing.
