P0415 Code - Secondary Air Injection System Switching Valve 'B' Circuit Malfunction

Quick Answer

When the engine is cold, the secondary air injection system helps reduce emissions by injecting fresh air into the exhaust system, promoting the combustion of unburned hydrocarbons. Common causes include Faulty secondary air injection switching valve 'B', Wiring issues or electrical connection problems, Vacuum leaks in the system. 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.
