What happens to the secondary air injection system?
Therefore, preventing the exhaust fumes from, leaking back into the secondary air injection system. When the air pump diverter valve fails, it can lead to a variety of problems. In addition to a significant increase in the vehicle’s, tailpipe emissions.
What are the symptoms of a bad air injection pump?
One of the early symptoms of a bad secondary air injection pump is the Check Engine warning light turning on. The engine control unit can automatically detect when the secondary air injection pump has a problem.
Why do we need an air injection system?
All we have to do is introduce some oxygen, than any unburned fuel will ignite. So, the air injection smog pump pushes air into the exhaust system, right after the exhaust manifold. Therefore, helping intercept and burn those unburned fuels. Above all, the system is critical to help engines achieve government emissions standards.

Where does the air come from for air injection?
A sensitive reed valve assembly called the aspirator valve is placed in the air injection pumping, which draws its air directly from the clean side of the air filter. During engine idle, brief but periodic negative pressure pulses in the exhaust system draw air through the aspirator valve and into the exhaust stream at the catalytic converter.
