SOURCE: where is the oxygen sensor
there should be 2,both are in the exhaust 1 behind the cat.converter & 1 upstream
if the truck has dual exhaust it may have more than the 2.if your reading codes it will
list them as bank 1 sensor 1 or 2. sensor 1= upstream 2 = behind cat

SOURCE: I would like to know
From my research, there are multiple O2 sensors on the exhaust system. They can be found near the catalytic converter, before and after it. O2 sensors are easy to find by the wires sticking out of the exhaust system and the mounting bungs for them.
