question about o2 codes

[james 27882]

last week I got the o2 failure code on bank 2 downstream, went to auto zone and got a bosch replacement and put that aggravaitting bastard in...yesterday I get a p0411 and then a few minutes later I get the p0430... my question is would the junk bosch cause the p0411 or would a bad secondary pump relay cause the p0430 code. I ordered a motorcraft o2 sensor from rockauto.com just in case but it wont be here til Thursday.
