Default DTC Error Codes

lurking through the hdforums tonight and figured I would search for DTC codes and how to look at them. went out and checked them out and to my surprise I have a few.
p0134
p0154
p0031
pn 31881-10

My question is, with my PCV with auto tune are these codes expected? I know the first two are 02 sensors not sure what the third is but I read a thread tonight where another guy was getting the exact three codes and sounded like that was normal for my setup.

Yep! Absolutely normal! 34 & 54 are fr & rr 02 sensors and 031 is the sensor heater.

All three are normal. When you disconnected the 02 sensors you also disconnected the heater.

So it's ok that the heater is disconnected? my check engine light is on and I can't get rid of the code p0031. Is there a certain plug or something I need or do I basically just need to clear the code?
