Replaced 2 O2 Sensors And The Engine Light Is Still On?

[hankkosovo]

Hey guys, A few weeks ago my engine light came on, the cars under warranty so I thought no big deal, I took it to a garage the diagnosed it as an o2 sensor (which is what I was hoping) and replaced it. On the way home, the light came back on, so I took it back and the again diagnosed it as an o2 sensor, so they replaced a second one, and now on the way home, the light came on again, for the third time.

I'm just looking for some general advice really, is it possible it could be another problem that isn't getting diagnosed, Is it possible that it still could be the o2 sensor?

Also, the car is an 05 is that makes any difference.

Thanks.
