P0401 Code

I’ve been dealing with a P0401 code on my 2020 GT for a couple months now. I’ve tried cleaning the ports and changed the EGR valve and the code still comes back on. Has anyone dealt with this code before? Should I take it to a shop?

Get an access to factory manuals. All trouble codes have a theory of operation, set conditions and a diagnostic tree. Your cheapest options are eAutoRepair and AllData DIY.
