The problem here is diagnostic fault codes never say to replace a part or that one is bad. They only indicate the circuit or system that needs further diagnosis, or the unacceptable operating condition. When a part is referenced in a fault code, it is actually the cause of that code about half of the time. Before we waste your money on parts, we have to rule out wiring and connector terminal problems in that circuit.
Some web sites provide suggestions on what it will take to solve a fault code based on previous experience, but there is no way to know which of the half dozen solutions will be the right one. What has happened is you were sold the part most likely to solve the problem, but the circuit should have diagnosed first.
You also never listed the exact fault code number. There are well over two dozen codes related to oxygen sensors, and they mean very different things and require different diagnostic steps. The place to start is by knowing the fault code number, then we can determine how to diagnose the cause.
