I don't find the P0442 code for a 2000S in my Bentley book but lets assume it is the same as the P0442 code for earlier year Boxsters.

You have done recent work on the AOS and the Evap system.

The P0442 is for a micro leak in the Fuel tank ventilation system.
Relates to the Evap system.

I believe all your other codes which are O2 sensor related are triggered by the micro leak in the fuel tank ventilation system.
So I would find and correct the micro leak problem first.
Then erase all codes and see how you go.

You may have not gotten something just right when you worked on the Evap system.
Or disturbed something when doing work on the Evap or AOS.

Let us know how you go I always like to know end results.

Blue62 is a good hand. Helped me lots when I was doing my O2 sensor changeouts.

I would swap out the gas cap 1st. Heard many times that solves a bunch of fuel related issues.

You sent me down the correct path, it was a short walk, I had intalialy discounted the gascap as I had just replaced it. However, I had fuelled up that day. The gas gap was cross threaded. Reinstlled and probem solved.

BTW, I see you are in Washington state, quite close by forum standards.

You have a friend at the beach.

Hmmm surf fishing.
Glad you got it sorted
I may have sent you down the right path but Zorro hit the nail on the head
