Years later I’m doing the same google search today
I got half engine light and same throttle codes
The car would surge/vibrate and when I finally got to the shoulder rpms bounced 2k to 500 and so on
This reset got me back on the highway. It works.
FYI MHD throttle reset was the first thing I tried and properly waited the 30 seconds but no go.
Thought I’d post for the next person
