well i just traded my freind a set of my old tires for a brand new edge easy.... seams to work good but i only have it on the medium setting because when its on hight the check engine light comes on. does anyone know what might make it do this ?

My buddy had the same thing I think its normal but when its on full I think it throws a code that says something on injection pressure High/Low but not sure. I wouldn't be to worried about it

Souns like your HPOP is goin out and cant keep up with the demand in oil to run the injectors properly on the high setting.

That is what I was thinking, but to be more certain on that diagnosis we need to know what code is getting set, not merely that the check engine light comes on.
