There are several O2 sensors on that vehicle and they are all threaded into the exhaust system at various points.

It is the Oxygen sensor behind the catalytic converter.
P0161 is a Lambda heater sensor malfunction (oxygen sensor) located in the front section of the exhaust system.
There is 2 of them and they both are underneith the intake manifold. You will have to remove the intake to service them and to even see them.
That truck has 4 o2 sensors, there are two catalyst converters on this truck as well. Bank one (Driver side), bank 2 (passenger side), sensor one is before the catalyst converter , sensor 2 after. There are two catalyst converters on this truck as well. Follow the exhaust system back from the engine and you will find them. A scan will tell you which one you are looking for.
