"Given the high numbers though for NOx, CO & CO2, and the slightly carboned

voltage through the sensor(if it's in there), but that is also part of the
next diagnosis."

I posted the following link a while back which should help understand how to
test an O2 sensor correctly.  Be warned: it is not quite as simple as
testing a coolant temp. sender or the like.
