So my check engine light came on and threw a P0138 CEL which from my quick research is Bank one Sensor 2. Does anyone know what the part number for this sensor would be. On rock auto I assume its downstream, but is it left or right? Also I recently had my starter replaced which i know requires removing the Y-pipe. Is it possible when they did so, they removed the sensor or installed the Y-pipe in a way that there was a leak that set the sensor off? Any help would be appreciated, thanks.

I believe that bank 1 is on the passenger side, and sensor 2 is the downstream one. I believe that 89467-30010 is the correct part number, but there were several listed so it was hard to tell (maybe the right one depends on your model year?).

If the shop installed the exhaust incorrectly or didn't put in new gaskets, you could have a leak. That would probably cause a P0430 though – I replaced the exhaust manifold gaskets on my dad's 2GS a couple weeks ago for this very reason. Maybe your shop damaged one of the sensor's wires when they took the Y pipe off. Or it just went bad, I mean they do exist in a very harsh environment!

Yeah I figured it out and got a denso sensor. The Y pipe was replaced only 2 years ago so everything should come apart relatively easily. Thankfully the passenger side is easily accessible and. I'm thinking I won't need to remove the passenger seat to get to it. I think it was just a coincidence, sucks but it happens. Rather get it all out of the way now I guess
