FI TP install problem help

persiani

i got my FI RTP and FI non res CBE installed yesterday and now i am throwing CEL p0031 and p01148, the 1148 is being thrown because of the the 0031 and what is making it so hard for me to figure out is, p0031 is primary sensor 1, bank 1 ( passenger side) and its calling for out of loop ( low voltage), what is making it so hard for me to figure out is when installing the test pipes, no tools or anything came remotley near the primary 02 sensor which is on the header..... and all the harness and connections are tight........ im trying to see if its a blown fuse of the heated oxy sensor that might have blown but no matter where i look i cannot figure out where that fuse is...

Somebody help me !!!, P.s the code comes instantly back on once cleared, so its being triggered alot..
