Just as title describes. 2020 had car for about a year, no issues. Got a CEL last month for P0496. Had the Purge Valve replaced by my trusty shop. 2 weeks after that, now getting P04F0.
Is this common? Any suggestions?
I have no issues or observations of any kind. This new code did not pop on soon after filling up with Gas. I did very that the fuel cap door is closing properly, even wiped it (this was on initial CEL for P0496, after resetting, initial CEL came back)
