P2415 Code…. Need help resolving issue

i just re installed the OEM exhaust and in the process i installed a new o2 sensor(passenger side pre-cat). i don't know if that has something to do with it or not. regardless can someone help me resolve the issue or at least point me in the right direction? the code is P2415 - Powertrain - O2 Sensor exhaust Error Bank2 Sensor 1…… i have searched and i can't find a definitive answer on which sensor it is.
