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

The "left" side of the engine is the driver's side.
The Engine Coolant Temperature (ECT) sensor is a thermistor (a device which changes resistance or voltage as temperature changes). The sensor detects the temperature of engine coolant and provides a corresponding signal to the PCM (Powertrain Control Module - aka "the car's computer").
The ECT sensor is mounted in the following locations (small Ford engines):
1.8L engines: in the cylinder head
1.9L engines: threaded into the heater hose inlet pipe
2.0L engines: at the left rear of the engine
2.0L Zetec Engine
(1) Partially drain the engine cooling system using a clean container. If coolant is in good condition, retain for reuse.
(2) Disconnect the battery ground cable.
(3) Disconnect the electrical wiring connector from the engine coolant temperature (ECT) sensor.
(4) Remove the retaining clip and the ECT sensor.
Fig. 1 Escort ZX2 ECT sensor - The retaining clip is removed (at the solid arrow). Withdraw ECT sensor by gently wiggling/pulling in the direction of the dashed arrow.
Coat the ECT sensor O-ring with clean coolant prior to installation.
(1) Replace the retaining clip and the ECT sensor.
(2) Connect the electrical wiring connector from the Engine Coolant Temperature (ECT) sensor.
(3) Connect the battery ground cable.
(4) Refill the engine cooling system. An inexpensive plastic "Radiator Funnel" will help with this task.
