throttle valve

[mzalusky@comcast.net]

hey all;

first thing, my keyboard on my pc is not working, pardon the grammar.
  I own a 2016 RT1200LC. I have this code that shows up ever so often. i turn the ignition off and back on the fault clears and the bike runs fine. Any ideas where to look. I am an above average mechanic and a fair electric guy.
Need some help. Here is the code.
