On a Lexus RX 300, the oxygen sensor is typically located in the exhaust system. There are usually two sensors: one before the catalytic converter (upstream) and one after it (downstream). The upstream sensor is generally found on the exhaust manifold or in the exhaust pipe close to the engine, while the downstream sensor is located after the catalytic converter. Always consult the vehicle's service manual for precise locations and specifications.
