2009 Aveo down stream O2 sensor fuse location

[Brian Howden]

I have a 2009 Aveo with 50K miles on it. I got a DTC of P0036 / P0138 / P0141 which all point to the heater circuit of the downstream O2 sensor. An ohm meter showed open on all combinations of the 4 pins so I bought a new NTK sensor with the correct plug on it and installed it. A few minutes later I am getting a P0054 which looks like a variation of the heater circuit for the down stream O2 sensor. Google has not been a lot of help other than check the fuse but I have not been able to find a location for the correct fuse.

Does anybody have any suggestions for where the fuse is located or other things I should be checking? Thanks in advance.
