I'll give a bit of history first of all
Bought the car (57 reg) in Feb/March 2015, first viewing took it a drive couple of minor problems, one of which being the EML is on, no biggie dealer will reset, picked the car up a week later EML still on & dealer reset in front of me
Code P0133 Heated oxygen sensor (HO2S) 1, bank 1 -slow response
Fast forward a couple of months and its back on, same P0133, reset myself and on my way. Couple of months later its back on again P0133, this time I've changed the o2 sensor for a Bosch part (OE equivalent) all is fine & dandy
Again a couple of months later its on again, guess what code? so this time I've changed to a genuine Fiat part & by now its MoT time, Failed it on emissions, fuel treatment & spirited drive gets it through
Next up is a remap by Angel Tuning Scotland, mapped ok however Paul feels its down on power, but still, running good for over a year and with new clutch & timing belt/water pump and a battery gets me up to this point
Driving up the A1, filled up with Tesco Momentum 99ron, doing around 60mph, EML flags up again, got the code reader out back home and yep P0133, again :bang:
Now bar a small hole (like, very small) in the down/middle pipe there are no noticable exhaust leaks pre-cat or anything else I can think of to cause it
Anything else worth checking before chucking a new sensor in?
