Were is it located at?
Bank one is the side with cylinder one, and sensor one is in front of the catalytic converter.
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.

Hi the oxygen sensor is located in the exhaust it will either be just before or just after the catalytic converter it will be bolted into the exhaust and will have two wires coming off it that connect into the wiring loom near the engine.
