    Do you know what make or even part number of sensor has been fitted? Stupid question but I have to ask, it is the sensor after the cat which has been changed isn't it? I had a situation like this years ago and the only was it would behave on the heater side was to fit a genuine sensor, even a proper Bosch one triggered the fault as it's heater current drain was too low.

    no idea what make or the part number of the sensor that was fitted. From what I have looked up bank 1 sensor 2 is the sensor after the cat yea, although from looking this up Im starting to wonder did the mechanic I went to only change the sensor before the cat.

    It would not be the first time I have seen that and I expect, not the last.
