Check the exhaust system first in the engine compartment area where the Manifold connects to the exhaust pipes then check under the vehicle just before the Catylatic converter and after. Some vehicles have 2 and upstream and down stream sensor. It is usually the upstream or the one closest to the engine that goes bad.

What is a oxygen sensor on a Oldsmobile silhouette


oxygen sensors tell your engine if it needs more or less fuel to operate correctly, they are located in your exhaust system, one before the catalytic convertor and one after, if replacing yourself make sure exhaust is hot to ensure you do not strip out the threads

My 2002 olds silhouette had a fault code for bank 1 oxygen sensor #2.So I changed the oxygen after the converter and the fault code is still there.I did un-hook the battery to clear the code.


Bank 1 sensors are all the o2 sensors before the converter. Bank 2 sensors are all after the converter.On bank 1 there is 1 for each side of the exhaust manifolds. Bank 1 sensor 1 is on the side ot the engine that #1 cylinder is on. Bank 1 sensor 2 is on the other side. On front wheel drive GM vehicles sensor 1 is in front,2 is in back, but stiil in front of catalytic converter.
