this i would take to a reputable ASE shop or the dealer.
codes pointing to sensors do not necessarily mean there's a bad sensor. sensors should be tested. checked good, then the components and or **environment** they monitor is in question.
o2 sensors monitor exhaust **environments**. not any one component. many components can create an exhaust condition that is outside the o2 sensor range. the exhaust environment needs to be diagnosed as a whole. not necessarily replacing the o2 sensor.
in this case, it's likely a low volt wire to the sensor, or more likely, a fuel mixture issue associated with that sensor. prolly a leaky injector.
