Answer 2

There are 4 of these sensors you will need the find the codes first and replace the correct one.

1. Bank 1 Sensor 1 is located on the passenger side before the catalytic converter (on the header aka exhaust manifold)

2. Bank 1 Sensor 2 is located on the dricer side after the header (exhaust manifold) on the catalytic converter

3. Bank 2 Sensor 1 is located on the passenger side before the catalytic converter on the header aka exhaust manifold

4. Bank 2 Sensor 2 is located on the dricer side after the header (exhaust manifold) on the catalytic converter

it probably wont be a fuse but you can always check it, it is on the passenger side near the engine bay.
