Question about 2001 Ford Escape
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

SOURCE: i'm getting codes with obd
If the O2 Sensors are original,you could just change the front 2
The ones closest to the engine.
Any other issue you need to actually diagnose, as codes
are for just that reason
They don't ever tell you to replace anything
Running rough is more the O2 Sensors
Ignition Coils going bad
