You stated that:

Diagnostic trouble code (DTC) EFI-621 (Fuel tank pressure sensor, signal) is stored if the engine control module (ECM) receives a signal from the tank pressure sensor corresponding to a pressure above 2.95 kPa (signal high) or below -2.88 kPa (signal low).

So does that mean that it could be due to a 'low' sensor to the tank due to a big leak in a hose? Looking at all the hoses in my V70, so many of them seem to be deteriorating, that I could believe that.
