Opinions please, EML on with code P0140 O2 sensor no activity detected B1 S2. Does this mean sensor 2. After cat? Gas readings are CO 9.5% O2 .51 CO2 9.8 HC 723 with lambda at .76. It is in closed loop. O2 sensor data: STFT -25% LTFT 25% (O2 A/fs Mon incomplete) (O2 FT B1-S2 99% )Been in trade for over 30 years but I am quite new to using a scanner (solus) but do know that the LTFT has tried to correct the fuel readings but too far out. Before scanner day's with this high a CO reading I would go for a before CAT O2 sensor. I have ordered new sensor and getting fitted on Monday. Some reading above I do not fully understand.In Brackets. Sorry for being dim. What do you think.
