Where are the oxygen sensor located on this vehicle?

Hello,

This vehicle is equipped with 2 oxygen sensors.
One is located on the exhaust manifold, which is the upstream sensor; the second one is located after the catalytic converter on the exhaust pipe, which is the downstream sensor.

Here is a helpful guide on oxygen sensor replacement:

Please let me know if you have any questions.
Thank you.
