You have problems with your evap system, get it tested.
Check your Oxygen sensor wiring, if it is fine, replace them.

The fact that you have p0131 and p0132 at the same time leads me to believe that you unplugged that sensor with the key on and set the code by mistake. Find the broken evap hose and clear all the codes. Drive it till the cel comes back on and then work with thoses codes. Those o2 sensors share a common ground as well
