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.
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?
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.
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.

What do I need to check an idle air control valve?
If your vehicle was built prior to 1996, you will need an OBD I scanner. Vehicles made after 1996 will need an OBD II scanner. Connect the code scanner to the port beneath the dashboard and turn it on. Once connected, use the scanner to bring up the error codes making the check engine light come on.
What causes an engine to spit out the intake manifold?
With the valves open, result of the ignition will be spitting and it will manifest through the intake manifold. This is often referred to as the ignition timing problem. Spark plugs might seem an afterthought but they really are the bones for an engine to function normally.
What happens when the air injection pump is not working?
But in situations when the secondary air injection pump is not working, you can expect the RPM to drop. This may cause the car to vibrate or even stall as noted above. 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.
Where is the air injection pump located on a car?
Typically, the Check Engine Light will be illuminated and diagnostic trouble codes (DTCs) will be stored in the PCM. Step 1: Locate the air injection pump. The air pump is at the front of the engine with the serpentine belt wrapped around it.

What are the components of an air injection pump?
The air injection system introduces oxygen into the exhaust engine at certain times to reduce emissions. Typical system components include the PCM, air injection relay, air injection hoses, valves and the pump. The air injection pump can be either belt driven or electric – for this article, we will focus on the belt-driven design.
Do you need to replace the air pump in a TSB?
TSB will require replacement for the air pump and the installation of a new secondary injection hose. Simply replacing the air pump will not always solve the problem, as a matter of fact, it may come back over and over again. When replacing the air pump, it is important to clean the hoses and replace he one-way check valve.
When your engine is idling, check the tachometer and see what the current RPM is. The normal RPM of an idle engine is somewhere between 600 to 1,000 RPM. But in situations when the secondary air injection pump is not working, you can expect the RPM to drop. This may cause the car to vibrate or even stall as noted above.
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.
Where does the secondary air pump go in a car?
The secondary-air pump draws in ambient air and injects it into the exhaust manifold downstream of the exhaust valves. There is a separate integrated air filter if the air is not drawn in from the intake system but rather directly from the engine compartment.
Why do you need a secondary air pump?
Another noteworthy purpose of the secondary air pump is to prevent damage to the exhaust system by blowing out any accumulated water vapor that could freeze the system. This function is necessary when the system detects the ambient air is below -10 degrees C (-14 degrees F).
How does the secondary air injection system work?
The secondary air injection system injects air into the exhaust to help lower emissions. Most of the time, P0411 is going to be caused by a failure in this pump or the one way check valve.
Can a p0411 leak cause a Volkswagen Beetle to break down?
An exhaust leak can cause the ECM to think that the AIR system is not working right. Look for damage to the exhaust system. If there’s a leak, you should be able to hear it. P0411 in the Volkswagen Beetle is not likely to cause the vehicle to break down, but can affect drivability.
