2008 Mazda 3 code P2274

[gorent]

I have a code P2274 popping up on my 08 mazda 3 Gt (2.3L) and have changed the forward oxygen sensor to try to correct and this did not work. Light has not come on, but code does appear on scanner. They say this means: oxy sensor stuck lean (bank 1-sensor 3). Has anyone corrected this code and were do I go from here???

sensor 3 would be the one rearward of the cataltetic convertor

Thank you! They say there are only two oxy sensor's on this model, that is why i changed the forward one first. I will check out rear one next and hope that is it. I do not have any exaust or intake leaks I can find! Thanks again!

Thank you everyone! It was the #3 oxygen sensor all the way in rear of exaust. I replaced and problem cured!
