p0152 and p0154 and p0051 i have in genesis coupe 2010which o2 sensor should be replaced?

Question

i have these codes
p0152 , p0154 , p0051 and also p0019 that i think timing is related to o2 sensor
the acceleration is really decreased
i want to purchase an o2 sensor and i dont know which sensor should be bought

Answer 1

P0152 - 02 sensor circuit high voltage Bank 2 sensor 1

P0154 - 02 sensor circuit no activity detected Bank 2 sensor 1

P0051 - 02 sensor circuit heater control circuit low Bank 2 sensor 1

P0019  Crank shaft position /camshaft postion Bank 2 sensor B 

What also need to be inspected is the CVVT (continous variable valve timing) and the operating at a normal condition, and also the oil control valve, which is possible to code P0019,  As for the 02 sensor location
