Equinox code P0054

HI guys i am having problems with my 2006 chevrolet equinox i had the code p0054 H02 Heater resistance ( bank 1 sensor 2). i replaced the o2 sensor after cat. i cleared the codes and it poped back the check engine light what is the next step to check should i check my wires and ground and power.

You need to get it hooked up to a scan tool to show data stream to see what all your 02 sensors are running at.
