Question: if your child has a temperature, do you replace the thermometer that told you the temperature, or work to find out WHY the kid has a fever?
A DTC (diagnostic trouble code) reporting a *lean* condition is telling you there's more AIR in the fuel mix than the computer was expecting.
In other words, air is sneaking / leaking into the engine - for example, a vacuum leak or leaking intake valve seals (which is common on Windstars).
A little more research into the 171 and 174 codes specific to the Taurus/Sables will avoid unnecessary 02 sensor replacements...
Also highly unlikely that both sides would have a failed O2 sensor at the same time, just common sense....... many things can cause a lean condition , even a weak fuel pump or plugged fuel filter , MAF sensor, injector seals and on, and on.

Where are the bank 2 oxygen sensors located on a 2000 Mercury Sable?
I'm going by the bank 2 sensor on my '98 Sable (which I recently replaced), but I did a quick search online, and it appears the 2000 is in the same place. It is mounted on the top of the exhaust pipe a few inches behind the catalytic converter. It's not too hard to replace if you have the O2 sensor socket. Getting at the connector at the other end of the pigtail is no treat, but it can be done with some patience and limber fingers.
