Check engine light came on, code P0057, downstream b2 s2. Removed sensor and replaced with a OEM part and reset lights. After about 25 - 35 miles lights came back on, same code.
compared both sensors (old and new) and they were identical.
what else could be causing the codes?

Welcome to 2CarPros.
The condition you have is related to a voltage issue. The first thing I suggest is having the battery load tested to confirm that isn't an issue. If the battery is good, I attached a few pics below which contain a flow chart of checks related to the code. It will require some electrical testing. Here are a few links to help:
