On a 2009 Lincoln MKS, Bank 2 Sensor 1 is located on the exhaust system, specifically on the side of the engine that corresponds to the passenger side. It's positioned before the catalytic converter, between the engine and the converter, and is responsible for measuring the oxygen content in the exhaust gases. To access it, you may need to lift the vehicle and potentially remove components for better visibility.
