Not true ^^ chrysler uses a 5 volt bias to their o2 sensors and as they heat up this 5 volts gets pulled down to your typically o2 voltage ranges.. this can be a great diagnostic aid in looking for o2 heater functionality

These o2 sensors are ground side switched by the pcm and its expecting to see 12 volts but the computer is seeing low volts on both upstream heater circuits, id check for a blown o2 heater fuse
