96 Prizm 02 Sensor Location?

Just had check engine light come on and Advanced said it was a P0136 code which means its the HO2S2 sensor which I think I located it before the Catalytic converter? Anyway the wire to it is coming inside the car and I been told I have to remove the carpet to get to it on the passenger side. Is this correct? Whats the best way to getting to it?

Thx

what you know about your sensor is right, and "simple", the sensor is the one behind the cat, pull the carpet and disconect it, remove the sensor and that's it! easy

or you could buy a new one cut the wires under the car, and splice the new one. Thats what I did and i didnt have any probs with it since
