There are four o2 sensors on this truck. one on each side just below the exhaust manifold, and one on each side behind the second catalytic converters. (just about even with the back of the front doors.

Location of the bank 1 sensor 2 O2 sensor on a 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

O2 sensor location

DTC P0156 indicates the output voltage of the downstream Heated Oxygen Sensor (HO2S) is less than some calibratable functional window. The possible causes are:
  1. Pinched, shorted and/or corroded wiring and pins.
  2. Crossed sensor wires
  3. Exhaust leaks.
  4. Contaminated HO2S.
  5. Bad HO2S.
Since you didnt specify the engine size in your vehicle - please see the diagram below for the location of the sensor(s)
