P0031 code?

Hey, what's up everyone? I am in need of some advice. I have a 2005 STI with 53,xxx on it with a TBE protuned. For the past two weeks now I have been throwing a code.
P0031 HO2S Heater Control Circuit Low (Bank 1 Sensor 1)

From what i have searched, this has to do with the o2 sensor. My question is, do I need to replace my o2 sensor? Is there anything I can do besides taking my AP and clearing these codes, or is my only option to replace it?

looks like you damaged your o2 sensor wiring when installing the tbe. easy way and probably only way is to buy a new o2 sensor or a used o2sensor

How does one damage the front air/fuel ratio sensor installing a tbe?

A new sensor = ~$200.
