Is it possible to work the other way and have the O2 sensor failing in that it runs leaner instead of richer?

On my Insight, I can get to both the sensors just by reaching down behind the engine. On your D17A, the exhaust is on the front of the engine rather than the back, so I'd expect it to be very easy. Just unplug the old sensor from the wiring harness (connector might be stiff), use a large crescent wrench to break it loose, unscrew and replace. It might be wise to put a bit of anti-seize on the threads when putting the new one in.
As for lean vs rich, I'm not sure.
