Sensor Reference Voltage "B" Circuit/Open

Hi!

Does anyone know which sensors that are connected to Referens Voltage circuit "B" on a 2010 skoda fabid 1.4tdi greenline? (I belive it is sometimes referred to as “Circuit 2” as well?). It apparently differs between cars?

I keep getting faultcodes as shown down below, and i would like som help regarding where to start searching. The MAF and throttlebody are already replaced with now difference.
