Help, Codes 520331, 520332

2016 Turbo, 3800 miles, 480 hours. Any help on what to check. These codes come intermittently. No rhyme or reason. Machine can be cold or I can go all day and it will throw these codes? Iíve hard wired the voltage regulator, wires got hot and melted the plugs. Had regulator tested and it checked out fine. Replaced knock sensor and looked for wiring issues. Found nothing obvious. Put new belt on? Polaris tech hooked it up to his computer and said everything was in spec? Codes will clear eventually, but again randomly. Sometimes quick and sometimes it takes awhile. Iím going to throw a new set of plugs in as itís still the original set. Thanks in advance.

I went through the wiring harness and found no obvious issues. Tested the knock sensor wires straight to the ecm and found no issues? So any suggestions would be greatly appreciated? This has been going on for a few months, so I know it’s not fuel related. Always run 91 nonethenol fuel.
