How do you fix a P0411 on a 2007 Saturn Ion?

A P0411 code on a 2007 Saturn Ion indicates an issue with the secondary air injection system, often due to a malfunctioning air pump, clogged hoses, or faulty check valves. To fix it, first inspect the air pump and hoses for damage or blockages, then test the electrical connections and fuses. If the pump is faulty, replace it; if the system is clear, check the check valves for proper operation. Finally, clear the code and run a test drive to ensure the issue is resolved.
