Where are the oxygen sensors on 2002 Hyundai 350xg?

On a 2002 Hyundai 350XG, the oxygen sensors are typically located in two main areas: one is positioned in the exhaust manifold or close to the engine, known as the upstream sensor, while the other is located further down the exhaust system, after the catalytic converter, referred to as the downstream sensor. To access them, you may need to lift the vehicle and remove any heat shields if present. Make sure to consult a repair manual for specific guidance on your model.
