Sirspidey Posted April 16, 2018 Share Posted April 16, 2018 Hi all it’s been a while since I’ve had to post on here, but just wanted some advice. So yesterday I had the dreaded CEL come on. Plugged in my reader today and I had the code p0031 ho2 Hester pow bank 1 come up. Had a quick look on internet and most say it’s the o2 sensor at fault, well kinda worked that out for myself. Now I just wanted an expert to confirm that my best cause of action is to replace the sensor or could it be something else?? The car runs fine, if anything maybe a slight hesitation when you blip the throttle and I have thought for a while the the car was ‘smelling’ of fuel. Any thoughts please, before I order the part up. Many thanksJeffEdit also I’ll add I cleared the codes and started the car, cel disappeared for a moment then came straight back and had the same codes.
