Secondary Air Injection System
The secondary air injection system of your vehicle helps provide clean air to your exhaust system to reduce your exhaust emissions. The exact locations in which the clean air is injected varies by car model. Older model vehicles utilize a belt-driven pump and vacuum-operated switching valves, while newer vehicles often use an electric pump and computer-controlled switching as needed. The secondary air injection system is typically controlled by the vehicle’s power train control module, which manages the vehicle’s power train and emission system among other things.
Signs of a bad secondary air injection system
