Oxygen sensor heating before catalytic converter activation.

I m always a bit suspicious when things happen while the car is in a garage for repair however is this most likely just a coincidence. The fluctuating values of the residual oxygen are sent to the engine control unit as a voltage signal. The vehicle had come from another shop which had already replaced the oxygen sensor. The broadband oxygen sensor continuously measures the residual oxygen in the exhaust gas.

The vehicle had repeatedly returned with a code of p0031 o2 sensor b1s1 low current flow heater circuit failure open circuit. Open circuit 284e00 oxygen sensor after catalytic converter nernst voltage signal. Oxygen sensors are laid out in banks which refer to cylinders and in sensor numbers referring to before or after the catalytic converter. A lazy oxygen sensor might falsely indicate a catalytic converter problem yet not set a dtc for itself.

There is generally no disagreement with the role in catalyst testing. July 26 2016. That code is for the sensor heater post cat sensor. I have two questions regarding the following fault code.
