okay I took these pics of a vacuum hose that appears to be broken off, it is the very bottom line. It starts under the master cylinder and comes around and is broken off. Could this be the reason for the 1415 code? I cant figure out where it goes.

 

Axle breather.

P1415 is from SAI system, see attached, may involve front O2 as well.
