I am getting the following fault codes on my 2012 Cruze. There are no apparent performance issues. I haven't had a chance to monitor the fuel efficiency. Could someone help me figure out what is wrong?

P015B O2 Sensor Delayed Response - Lean to Rich Bank 1 Sensor 1
P0171 System too lean, bank 1
P2270 O2 Sensor Signal Biased/Stuck Lean Bank 1 Sensor 2
B2aaa

Thank you very much
