Need help Code 35 and 49

[3500 dually]

Well still kinda new to the site, but everyone help me on the OPS repair. Now this past monday the truck died 6 times but started right back up. I flash codes today which gave me a 35 "Turbo charger bypass valve control circuit high" and a 49 " T/S charger turbine overspeed. Any ideas?
Got defination of codes from the DTC's at top.

Those codes are wrong for these trucks

Could be grounds or a pmd. Check your pmd conections on the ext.

Thanks, that sounds interesting and codes look more related to what happen. Whats funny is this happen this past monday but has not died sense then. My truck did sit this past weekend and was not driven. I did have a heat sink relocated at top of intake, I guess I will need to buy a bumper mounted pmd. what are your thoughts on that.

I had mine on the intake, it lasted 5 months/3000 miles. It's now in the bumper. That was 3 years ago.

Mine is a SSD heatsink. IIRC it was about $400 four years ago last January. It lasted to May that year
