P1283 A/F SENSOR 1 (B2)

That's sensor 1, bank 2.

 

What would cause this, any ideas? I have a pop charger, kinetix SSV, full exhaust. I want to take it to the dealership but something tells me they are going to blame it on one of my few mods. Iv had all of the above installed for over 8 months so I know its not from adding anything. I appreciate the help.

 

It could be that the sensor has gone bad or it could mean that it's reading either too high or low. Do a search on "P1283" and you'll get a bunch of hits. Those threads will give you some ideas of stuff to look into.
