One of them is a front heated o2 sensor, the other is a rear heated o2 sensor. I don't think they are the same. But your local Nissan parts shop would be able to verify that for you.

The aren't the same. The two front O2 sensors are the same but the rear is a different one. Go to www.oxygensensors.com and buy one of each. Then, read the How-To sticky for my guide to replace them.
