On a 1997 Toyota T100 V6, the oxygen (O2) sensors are located in two main places: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream O2 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. To access them, you may need to lift the vehicle and may require special tools to remove them. Always ensure the engine is cool before attempting to work on the exhaust system.
