Theirs 4 of them .Its a bit confusseing how its set up .
You have bank sensor 1 first one drivers side y pipe
B# 1 sensor # 2 y pipe in front of CAT
B # 1 sensor #3 behind CAT down stream
B #2 sensor # 1 Y pipe but passanger side.
Don't worry about upstream or down stream on this vehicle they are all the same and are interchangable.

Ther are at leat 3 and maybe 4 o-2 sensors in that particular truck...one on each exaust pipe coming down from manifold...and one after convertor on each bank....Pass.side before convertor is bank one,sensor one ..behind convertor is bank one sensor two..drivers side before convertor is bank two,sensor one...behind convertor is bank two sensor two(If equipped with four....scan will tell you which one is bad....good luck..lee

HI, click the link below to be directed to a full diagram that will show you the actual location of the sensor. 718 will be the actual sensor to extract and 739 is the mounting screw for the KS.

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.

If you look from under the vehicle you should see it, instead of from the top.

There is a special socket for O2 sensors which allow the wires to stick out and not get twisted up. It's not expensive and available at most auto parts stores. Disconnect the sensor from the wiring harness, with the plug and then use the socket to remove and replace the new sensor. Re-connect electrical plug.
