bank 2 sensor 1 problem code p0154 showing up. on 2008 Acura TL

I replaced the bank 2 sensor 1, than my engine light when away the next day it returned. I went with a bosch o2 sensor, does brand matter?Or Do I have a bad sensor? Or do I need to replace the other sensor in front next to the fan as well since they work together please help I dont want to take it to the dealer and pay through the nose for something I can change myself.
