what does having damaged floor matts have to do with triggerig code P0220 on 2003 GMC Yukon XL Denali

i also get code P2135. this causes enginge to pretty much shut down and if something like damaged floor matts causes this, then that is very discomforting and dissapointing for GM. What the hell??
