Have P20E2 Codes.
I can clear the codes but eventually comes back on cold starts.
There's a lot of info on this but cant find any on where they are actually located.
Can someone educate me... Id like to change them out.
I think this is the exhaust layout.

Only happens on cold starts, I know the two communicate between each other and there is to be a variance between each other.
Additionally its the cheaper of the fix before it gets expensive. I have a real time scanner to pull up the operating data on them to pinpoint the exact one but would like to know their location too
