Answer 1

A P0411 code on a 2008 Chevy Cobalt indicates an issue with the secondary air injection system, which may be caused by a faulty air pump, a clogged air hose, or a malfunctioning relay. To fix it, first inspect the air pump and related components for any damage or blockages. Check the electrical connections and fuses, and replace any faulty parts as needed. Finally, clear the code with an OBD-II scanner and test drive the vehicle to ensure the issue is resolved.
