I'm in the same situation, and mine is due this month. I've read that O2 sensors that don't work properly will give you codes. Moreover, they say that if those stay within the correct voltage range (0.1 to 0.9 in this case, and downstream should try to stay at ~0.7 consistently, then they are OK. But I've also read that there are cases when O2 sensors get tired, and haven't triggered a code yet, but will affect their response time.

Anyway, you can get the Bosch ones from Amazon or RockAuto for about $80 to $100. The Universal one, which requires you to do the connector, is even cheaper at $60.

Here are the voltages for my working bank 1 and dying bank 2 cats.
