its located in the back of the motor.
The rear cylinders are 1-3-5 so that is bank 1. Front cylinders are 2-4-6 so that is bank 2. Follow the exhaust pipe from bank 2 and you will find the O2 sensor.
That code means that the oxygen sensor downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be. It could be a bad oxygen sensor, a bad catalytic converter or and exhaust leak.

Specifically, it is positioned before the catalytic converter on the driver's side of the engine. To access it, you may need to lift the vehicle and remove any necessary components for better visibility. Always ensure the engine is cool and take safety precautions when working on the exhaust system.
Bank 1 oxygen sensor is the closest to the engine exhaust manifold. It is usually can seen and replaced if necessary with open hood.
On a 2003 Toyota Highlander with a V6 3.0 engine, Bank 2 Sensor 1 refers to the upstream oxygen sensor located on the exhaust manifold on the driver's side. Bank 2 corresponds to the side of the engine that does not contain cylinder 1, which is the passenger side in this configuration. To access it, you may need to remove certain components for better visibility and reach.
