P0410 Lincoln Code - Secondary Air Injection System Malfunction

Quick Answer

The P0410 diagnostic trouble code (DTC) specifically pertains to a malfunction within the secondary air injection system of a Lincoln vehicle. Common causes include Faulty Air Pump: The air pump in the secondary air injection system may fail, leading to a decrease in air flow, Clogged Air Filter: A clogged air filter can restrict the flow of air through the system, triggering the P0410 code, Broken or Disconnected Hose: A broken or disconnected hose in the secondary air injection system can disrupt the flow of air. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
