So i got a CEL the other day, (P1130) not the issue. This means my truck may be fussing about the bank one sensor one, (02 sensor) So I'm gonna replace it IF this is the problem. I'm just trying to decide if its that, or the PCV valve.
My question is what are your guys bank 1 sensor 1 readings? Mine fluctuates to the -20's to positive teens. (it sticks the lower numbers most of the time) I'm assuming the negative means its running lean and positive is rich?? The website for my particular scangauge does not shed any light. Any ideas?
