Default P0430 for X308 (Please help...)

Hi Everyone,

My car is currently engine lights on after checked the code is P0430.
(P0430 JAGUAR - Catalyst System Efficiency Below Threshold Bank 2)

In case of P0430, which exact O2 sensor should be replaced?
Can I solve the problem by replacing the O2 sensor only?
Or is not it an O2 sensor problem?
I am in trouble because I do not know at all.

I would appreciate it if you could advise me.

Cheers
Michael
