trouble code on 95 Altima GXE

I have a 95 Altima GXE. The check engine light came on and I had the shop read the code, it is 0130 and 0325. I was told that it's usually the oxygen sensor that went bad and caused the knock sensor to send the trouble code too. My question is by changing the oxygen sensor can the problem go away or is there something else that can cause the oxygen sensor to go bad?

Thanks for your advice,
