Default CEL - P015C and P014E Help

Hi Guys;

I recently got these codes P015C and P014E. Long story short, I have the Invidia exhaust and the damn mechanic who put it on didn't tighten it enough. So I had a leak and I think my sensor went bad.

I've been looking and I couldn't find any type of diagram, or part number. Do you guys know anything about this that would help.

It is bank 2 sensor 1

Assuming you got the catback Invidia exhaust, then the tech should not have been anywhere near the Air Fuel Ratio sensors.
Bank 2 is the driver's side AF sensor...it's right above the cat and right below the three exhaust runners that come off the cylinder head.
Assuming your 2014 IS250 is RWD, the part number is 89465-53290.
