If the code is related to the O2 sensor, can one of these, or both, be the cause of the problem?

thanks quack for helping

edit: what does the o2 sensor?
Get that old dirty gas out and put in 91 octane...i think that should take of your check engine light.

Are you askin what does the o2 sensor do??
it measures the amount of oxygen in the engines exhaust gases before and after the cat.
