Where is the oxygen sensor on the 2003 Hyundai Santa Fe with the V6 2 point 7 liter engine located?

On the 2003 Hyundai Santa Fe with the 2.7-liter V6 engine, the oxygen sensors are located in two places: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor is typically found on the exhaust manifold or just before the catalytic converter, while the downstream sensor is located after the catalytic converter in the exhaust system. You may need to raise the vehicle for better access to the sensors.
