What happens when a secondary air injection pump wears down?
A secondary air injection pump that is wearing down can cause inconsistent power gaps from the engine. One minute the power may be fine, and the next it may be weak. If the pump is not replaced, the power will stay weak.
What do you need to know about a secondary air pump?
If you’re wondering what a secondary air injection pump is, you’re not alone. In this article, we’ll go over the purpose of the secondary are pump as well as the symptoms you should watch for that indicate the pump is failing. What Does a Secondary Air Pump Do? What Does a Secondary Air Pump Do?
How to troubleshoot a faulty secondary air system?
In most cases, a fault in the secondary air system can be identified by a scratching or whistling noise, or by the secondary air pump no longer working. In this technical video, we provide tips on troubleshooting and show how you can test the components in the secondary air system using simple methods. http://www.ms-motor-service.com/en/re…
Can a bad air injection pump cause engine stall?
A failed emissions test in conjunction with weak acceleration is a decent indicator that it is the pump’s fault. You may be driving normally and then suddenly experience engine stalling or hesitation in your vehicle. A secondary air injection pump that is wearing down can cause inconsistent power gaps from the engine.
How long does the secondary air pump run?
The secondary air pump only runs for 2 minutes just after starting a cold engine. Even less if the engine warms up quickly on a warm day. It pumps air into the exhaust stream when the engine is running rich.
When to replace a secondary air injection pump?
If you’ve already experienced engine stalling, poor acceleration, and a check engine warning light, then you need to have the secondary air injection pump checked out immediately. If it is proven to be the problem, have it replaced by a certified mechanic.
How does a secondary air injection system work?
This component is also called a smog pump, or an air pump, and it lies within the secondary air injection system of the vehicle. It can reduce carbon emissions by pumping fresh air from outside into the exhaust stream. By the time fumes leave the tailpipe, there are fewer hydrocarbon pollutants in them.

How does the secondary air pump reduce emissions?
The secondary air injection pump is an emissions component that lowers emissions by pumping in fresh air just before the catalytic converter.
How much does it cost to replace a secondary air pump?
Secondary Air Injection Pump Replacement Costs The average cost to replace a secondary air injection pump ranges from $250 to $400. This is significantly cheaper than replacing the primary air pump, which can cost from $600 to $700.

How do you close a secondary air ignition pump?
To do this, you have to detach the valve’s vacuum line and connect the pump to the valve. A hose fitting connects the combination valve to the secondary air ignition pump. Loosen the fitting and blow air inside with a little pressure, which must close the valve.
Where does the air pump go in a car?
The pump lies after the exhaust manifold and before the catalytic converter of the vehicle and it can reduce carbon emissions by pumping fresh air from outside into the exhaust stream. By the time fumes leave the tailpipe, there are fewer hydrocarbon pollutants in them. This promotes a safer environment by cutting down on air pollution outside.
