2018 T450 error codes M4622, H1222

[Brettc4]

2018 Bobcat t450 with 800 hrs. I was getting the H1222 error code first and after about a week the M4622 code started. M4622 code is intermittent. Should i check wiring harness or does this sound like a controller issue? Also since these issues have started it seems to bog down if the throttle is not set to low
