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.
