I recently had my check engine light came on and had a diagnostic run at AutoZone. The error code came to be P1520. I ran this by my friend's dad who is a Ford Mechanic and said that it was an O2 sensor. However, there are 2 sensors on my car. I am trying to figure out where the 2 sensors are, and how easy it will be to change these/figure out which one is faulty. Any help/reccommendations.

Thanks.

Your oxygen sensors are located on the exhaust system. One will be before the catalytic converter and the other after (closer to engine) converter. They simply unscrew and disconnect electrical connection to replace. To learn how to check your oxygen sensors before removing/replacing, follow the link below..
