My check engine light came on this morning so i pulled over and got my trusty sct tuner out and pulled the code it came up with p2198 which says 02 sensor signal biased/ stuck rich (b2 ,s1). Anyone know anything about this?

 

I'd probably replace the driver's side front sensor.

 

Your correct I just found that out thanks

 

Did the new O2 sensor cure the problem? Throwing the same code today.
