Got code P0130 O2 Sensor Circuit Malfunction (Bank 1 Sensor 1),

I have about 106k
Passenger side cat done last month and driver side covered under warrenty a couple years back.

I know im in need of new 02 sensors.
My question is- Is it front or rear 02 thats just before the cat curves I should be ordering?
and should I act quickly or is some thing bad going to happen :(
Or anything else I should be looking for??

Yes, it's the O2 sensor closest to the engine on the passenger side. May just be coincidence that it follows so close to the cat replacement since it is old, or it may be that the tip of O2 sensor was polluted (touched) when it was swapped from the old pipe to the new pipe.
