What does it mean to have a code po 430 on a 2003 ford expedition


My code book says"Catalyst Efficiency Below Threshold(Bank 2).This means the computer sees that the readings between the O2 sensor before and after the catalytic converter show that the converter isn't cleaning the exhaust enough.This could be the sensors or the converter.I'm leaning toward the converter,but this only a guess.(O2 sensors can become sluggish and not read accurately,but the computer would most likely set a code for one of the sensors as well).
