On a 2003 Oldsmobile Silhouette, the heated oxygen sensor (HO2S) bank 1 sensor 1 is located in the exhaust system, specifically upstream of the catalytic converter. It is typically found on the exhaust manifold or in the front pipe leading to the catalytic converter. This sensor monitors the oxygen levels in the exhaust gases to help regulate the engine's air-fuel mixture.
