My 2007 Ford Fusion with a 4. Cleaned mass air flow sensor and got 2 codes after starting. p0410 and p0491. Cleared codes and came back 1 week later. Should I change sensor? Could it be air pump?

codes do not identify bad parts, just failed systems. the 410 is a secondary air pump issue.

491 is also secondary flow.

do not clear the codes as this does nothing, the issue is still there.
