    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.

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    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.
