it may be a defective O2 sensor here is th difinition:
P0133 - Heated Oxygen Sensor (HO2S) Slow Response Bank 1 Sensor 1 , this is the sensor on the side of the engine that #1 cylinder is on, it is the sensor before the cat.

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

Bank 2 is passenger side, sensor 1 is the one up closest to the exhaust manifold. Plug in type (just remove old and plug back into the wiring harness connector) is about $90 at Autozone. You can get a cheaper one that you splice but it's confusing to understand which wires to splice together. Don't forget to buy the special socket, $10, to remove and install the sensor. It's split up the side for the wires. Forget trying to use an open end wrench, socket is best.
