Default 05 Elantra trouble shooting codes

I checked my check engine light and found the following codes:

P0036 HO2s heater control circuit bank 1 sensor 2
P2270 O2 sensor signal stuck lean bank 1 sensor 2

I recently replaced the downstream o2 sensor but it was a cheap one i found online. Does anyone know how to fix these issues and/or what kind of tests to run?

Did you ever solve your problem? I have the same two codes coming up. Should I just replace the O2 sensor? Any ideas?
