it depends. if it is a heater circuit, you may have replaced the correct sensor, there are 4 sensors, 2 upstream and 2 downstream, but the circuit is protected by a heater fuse which may have blown in the process.

Where is the heater fuse and is it hard to change? What I mean is, is it in the fuse box in the engine or is it an inline fuse?
