I have an 02 PT Cruiser that keeps throwing the check engine light. When I put my scan tool on it, it reads that the O2 sensor on bank 1 is not functioning right. My question is where are the O2 sensors located at on this car

These sensors are located before and after the converter.

Here is a video that will help with this on a similar vehicle:

Below you will find a diagram of the general locations of the sensors so please review this and the process to replace them.
