Code PO158.... o2 sensor bad? Says its a short related to the o2 sensor. I had my check engine light flash after a hard rip but it went out.... checked the codes and this is what i got. Anybody have this happen or expereince this code before?

I may just replace the o2 sensors and hopefully that will do it, however, i just got a dyno tune two days before the MIL light flash, would replacing the o2 sensors with new ones screw with my A/F ratio? Would i need to Dyno the girl again?
