ok i dont know what that does lol, but i need a new o2 sensor cause i have a check engine light on, do you think if i get the wideband would it fix the problem
 
I thought of the same idea originally when my 1st 02 sensor went bad and was throwing a CEL. You cannot use a wideband 02 to replace the stock narrow band.
