Question about 2001 Ford Windstar
OK. The Code bank 1 or 2, have to be acompained with a especific code number.
Because Bank 1 or 2, is Left side or Right side.
On windstar Bank 1 is at the firewall side, and Bank 2 is at the radiator side.
But the number of the Code will give the especific problem on any of the Banks. After that you gonna know what you have to fix.
OK I hope this information will help on your question.

well on my car these are reffering to the sensors in the exhaust, the upstream sensor(before the cat) and the downstream sensor(after the cat) the downstream sensor can act up if it is lazy or sluggish, or due to a bad catalytic converter or a clogged one. however there are sensors on the exhaust manifold which are determined by driver side or passenger,my opinion is to get a scanner for about $100 to $150 and you can figure out many of these codes yourself.

yes i would recommend replacing the o2 sensor, 9 times out of 10 it will correct the problem and they usually aren't too expensive for the saturn's

is this a 4 or 6 cylinder?
if a 4 cylinder it will only have 2 o2 sensors
V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor.
1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.
if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.

Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1)
What does that mean? Essentially the same as P0136 and P0137, a P0131 code refers to the first oxygen sensor on Bank 1.
P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.
Symptoms There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.
Causes A code P0131 may mean that one or more of the following has happened:
