These codes refer to high voltage on the heater control circuits of the O2 sensors. Check the ground G107 at right rear of engine compartment (passenger side). See attached picture. If ground is good then heater elements in the O2 sensors are burned out. Fix is to replace the four O2 sensors. The vehicle will still run and drive fine. The heaters in the sensors are just used to make the sensors react more quickly on a cold startup to reduce emissions. It will not harm anything to drive the vehicle as it is.
