FYI

I do have Richie's V2 Precats and V3 J-Pipe as well as ATLP Quad exhaust.

 

That's 02 sensor slow response, bank 1 sensor 2 (rear bottom sensor)....delete and reset, see if it comes back...if so, swap sensor with the front one (front rear) and see if you get the different code. If so, sensor's bad.

Its most likely set off by electrical fluctuations. They're sensitive to this and happens a lot.

 

hit map/guide menu and cancel all at once... then go through a few menus and you should be able to clear the code from the navs brain

 

when I turned the car on today CEL was gone and nothing in the Navi anymore...
