Check the heat shield on the catalytic converter
Under the vehicle bolted to the exhaust pipe.
On a 1999 Toyota Corolla, the oxygen sensor is typically located in the exhaust system. There are usually two sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor is found on the exhaust manifold or near the front of the catalytic converter, while the downstream sensor is located further along the exhaust pipe after the catalytic converter. You may need to lift the vehicle or access it from underneath for better visibility.
