The oxygen (O2) sensors are located in the exhaust system. There are
three O2 sensors and one Catalyst Monitor, one in each of the exhaust headers near each of the front
wheels and the third in the common exhaust pipe further back. A
special deep socket is available from any parts store to remove the
sensors. The socket has a **** down its length to accommodate the sensor
wire permanently attached. Simply disconnect the bullet connector and
unscrew the sensor.

Where is the location of an O2 sensor for bank sensor 1 on an 2011 Ford Taurus
Pass Side before the converter
SOURCE: I need to know which O2 sensors are which: Bank 1
bank one upstream oxygen sensor on exhaust manifold bank two oxygen sensor after catalytic converter.tell me what code you are getting.bank 1 sensor 1 fuel system is too rich fuel pressure too high fuel pressure regulator leaking or more than 1 fuel injector leaking. fuel contaminated.check spark plugs if black carbon color fuel system too rich. if you getting code bank 1 sensor 2 check for air leaks in the exhaust system, air leaks intake manifold.look for vacuum lines leaks,look for vacuum leaks pcv valve and hose and make egr valve not stuck open or gasket leak.
SOURCE: o2 sensor bank1 sensor 1
usually bank 1 sensor one is closest to the motor(guess) but you can look it up in a manual and just changing the 02 sensor is gonna fix it they are anywhere from 40 to 100 dollars hope it helps

bank 1 refers to the side of the engine that #1 cylinder is on , and sensor 2 refers to downstream , after the catalytic converter. , this link shows bank 1 on a 2001 nissan maxima V6 being on the firewall side . if you had a 4 cylinder it would be downstream after the catalytic converter .

Should be in the manifold on the back side closest to the firewall.

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter
You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks
Fig. Fig. 3: Oxygen sensor-4.3L engines
Fig. Fig. 4: Oxygen sensor-5.0L and 5.7L engines
Fig. Fig. 5: Oxygen sensor-7.4L engines
Oxygen sensors are always numbered like this:
Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2
Some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2
Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.
Sensor 1 is always the upstream sensor (the one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.
Hope helps (remember to rate this).
