It is a good idea if replacing one 02 Sensor to replace all of them at the same time. Location is- they screw into the exhaust pipes below the exhaust manifolds and before the muffler.( Very hard to miss them ). Make sure you have the codes cleared from the on board computers memory after repairs are finished. Good Luck and have a good XMASS,

Sensor 2 should be in or immediately after the catalytic converter for bank 1, assuming that its true dual exhaust and dual cat.
P0141-Bank1 Sensor2- code.--------
The "Sensor located
after catalytic converter".This o2 sensor needs to be replaced.-------
