Codes p0031, p1148

I’m looking across the forums but am stumped , will I need a new upstream sensor or will I just need a tune for throwing codes p0031 and p1148,

Installed ART pipes . Z1 said I need upstream sensor .

Google says verify the circuit before replacing the A/F sensor (upstream O2). It is possible that either the wire is broken/burnt through, the fuse blown or both. Link to FSM is in my sig.
