got a 2020 ram eco with 60k miles and driving two days ago, it threw the code p26fb saying bypass valve stuck. anyone having this issue. it seems to be driving fine drove about 300 miles and nothing seems off. is it an electrical issue? my coolant was a bit low could that be a problem?

I saw that and pulled that hose off checked air flow and it all seemed good, also checked the valve and it has the metal clinging noise when I let it go. engine light still on. going to drove it tomorrow see if it'll shut off but not sure what else to do besides bring it into dealer.
