O2 sensor pumping problem?!?!

Hey guys! I have an 09 c-63 and had the CEL come on with " O2 sensor pumping problem"
Bank 1 , sensor 2 . Has anyone ever gotten this code? And which side is bank 1 , so I can start with at least changing the sensor? Thanks again for all the usefull info on this site! Keep up the good work!

JB

Thanks for the response! Have you ever seen this code? And where can I find the fuses for the O2 sensors just so I can rule that out?

There is fuses in the trunk and the front under the hood.

Doubt its a fuse.

Probably need a new sensor. Don't go to the dealer, order online.
