The front

and I would replace both of then at the same time as when one goes bad the other is not far behind.

bank 2 sensor 1 is the precat sensor and rare normally the aftercast sensor fails first unless you hit some ice on the road which shocks the system and gives a fault code?

I'm really not sure, it happened last week in the morning. The ice is possible because it was around -4 degrees.

clear the code and if it comes back you have a problem but get the code it might be a simple solution
