A couple weeks back the rear most part of my splitter broke off slicing my
Bank 2 o2 sensor wire completely in half.
Trying to take the cheaper way out and to see of I could get away with it
I just replaced that o2 sensor " I know your supposed to replace them in pairs"
Anyway I throwing code p0057 bank 2 o2 sensor heater.
Is it possible that its throwing the code*because I didnt replace the bank 1 sensors so the old and new sensor arnt reading correctly??

 

You don't have to replace oxygen sensors in pairs. If you have a heater circuit code that means the sensor itself is bad. What brand did you install? Cars like to throw codes sometimes if you don't use factory O2 sensors. Either way you will need to install another bank 2 O2 sensor.
