SOURCE: where is the bank 2 sensor 1 located.
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.
Most GM engines have #1 cylinder located on the left bank, (or Driver's Side) of the engine,
So, the answer to your question would be that you are looking for the sensor located before the catalytic converter on the right (or Passenger Side) of the truck.

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: How do I change the heater fan speed control in a
On the back of the control panel there is a plastic connector that plugs into the fan speed control. You can unplug it and use a meter to find incoming (hotwire) take a jumper or a 6 inch peice of wire and insert it into the spade where the hot wire is wired to. Take the other end of the wire and insert it into the 1st spade in the plastic connector next to the hot wire spade this will let you know that the fan will run at the selected speed. Then pull the test wire out and plug it into the next spade and so on and so on. I am sure your fan will respond step by step , fan speed 1 then 2 and then 3. After you make this test you will know that your fan is ok. You will just have to replace the plastic connector with new spades in it. You should see some evidence of over heating on the old connector. It may be that you only need to unsnap the connector and then reconnet it and it will probably work fine. It has proberly just become partially unpluged. All the other info that I gave you early on was just to trouble shoot it. mike

SOURCE: were bank 1 sensor 2 located on a 1997 tahoe
bank 1 is the drivers side,and it is the down stream sensor,the one after the cat,converter,If this was helpful,please let us know,thank you.
SOURCE: where are bank 1 sensor 1, bank 2 sensor 1, bank 1
bank one sensor 1 is the bank of cylinders that number 1 spark plug is located in, bank 2 the other side, this assumes u have a V8, the sensor one location is the sensors that are BEFORE THE CATALYTIC CONVERTER, the sensors referred to as sensor 2 are after the ones AFTER THE CATALYTIC CONVERTER IN THE EXHAUST SYSTEM.
