CA Smog - throw P1128 code?

I took my '01 Boxster for its 2-year CA smog certification. It passed without any issue. But shortly after - next day - the car threw a p1128 code. Not sure if they are related but, I find it too coincidental that the car has never thrown a code, has a newer AOS, and suddenly p1128 pops after a smog cert.

Now I'm trying to chase down how to fix the code.

I had the same code thrown occasionally after replacing my AOS. Just the P1128, no others. Turned out it was the hose from the AOS to the throttle body. Hose wasn't seated well.

I had 1126 and 1128. Turned out to be a lose hose.
