Not sure what year that you are talking about, but in a 3.5L V6, 1999, you have 4 of them to replace. There are dual exhausts coming from the engine and there are two catalytic converters. There is an O2 sensor just before and one just after each converter. There is a special O2 sensor tool that you may be able to get on loan from maybe an Auto Zone or Checker auto store in order to remove and install them. They may make you purchase it and then give money back when you are done. They are a bit of a Wrestling match, especially on the right side, but with persistence it can be done. When you are reinstalling them, make sure that you put anti-seize compound on them in case you ever have to remove them again.
Yes, there is a diagram of the oxygen sensor location of a Isuzu Trooper. This diagram can be found in the cars maintenance manual.
on the exhaust manifold.
Its in the alternator
It appears that the 1993 Isuzu 3.2L V6 engine has just one oxygen sensor. It's a 4-wire type, located at the exhaust Y-pipe outlet. == ==

a trooper engine or a rodao engine
If the Trooper has the 3.5L v6, there are 4 SO2 sensors. There are two banks right and left, or bank 1 and bank 2 respectively. Then there is a sensor upstream from the catalytic converter on each bank (sensor 1) , and one down stream (sensor 2).Hope this helps/
