Get a code reader or use an analog VOM to read the codes. Use the library or buy a manual or read here in the tech section how to retrieve the codes. Spending money on an O2 sensor without knowing if it is dysfunctional is perhaps not the way to go. Find out what's wrong before replacing parts *****-nilly. That is why the codes were designed into the system, and made available with little effort.
It might just be a loose wire or a gas tank cap that needs tightening. Even a small vacuum line can cause codes.
