"Bank one" is the bank of cylinders that starts with the #1 cylinder. In this case this will be the bank of three cylinders that is closest to the firewall. Sensor #1 refers to the O2 sensor that is between the engine and the catalytic converter. So the Bank 1, sensor 1, will be the O2 sensor that is mounted in the rear exhaust manifold or tubing just before the cat.

if u have one oxygen sensor then u need to take a deep look at the bottom of ur car it will be somewhere at the Exhaust pipe if u have a catalytic converter then u will have two oxygen sensors one before the catalytic converter & the other will be after the catalytic converter. Note: the catalytic converter is located at after a little bit of beginning in Exhaust pipe.

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.
