Where is o2 sensor in 2003 suzuki XL7?

In a 2003 Suzuki XL7, the oxygen (O2) sensor is typically located in the exhaust system. There are usually two O2 sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor is generally found near the engine, while the downstream sensor is positioned further along the exhaust pipe, after the catalytic converter. For precise location, it's best to consult the vehicle's service manual.
