WHERE TO FIND MY O2 SENSOR

2003 Ford Explorer

Electrical problem
2003 Ford Explorer 6 cyl Four Wheel Drive Automatic 100000 miles

check engine light is on and code says its an o2 sensor. Where is my o2 sensor and is there a way to tell which one needs replaced since I believe here are 2?

You have 4 O2 sensors. What code did you get exactly? I need to actual code number. Example: P0301 is misfire cylinder 1, P0133 O2 sensor bank 1 sensor 1, slow response.
