How does the secondary air injection system work?
The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system. An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module ( PCM) grounds the Air pump relay control circuit which energizes the Air pump.
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 an air injection system smog pump work?
Air Injection System & Smog Pump. The air injection system (AIS) is designed to introduce clean air to the engine exhaust as it exits the exhaust manifold or exhaust headers. Exhaust gases are at their hottest as they leave the combustion chambers.
How does a pulse air injection system work?
If it appears there are missing parts or open ends seek repair assistance from a certified smog repair station before subjecting your vehicle to the smog inspection. For vehicles equipped with the pulse air injection system, the technician will only inspect the injection pipes and valves.

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 air pump work in a PCM?
The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves.
How does an air pump work on a Mercedes Benz?
P0410 Mercedes-benz Meaning. An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump.
How does the air combination valve solenoid circuit work?
The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The PCM enables both circuits simultaneously when Air system operations id desired.

What is the trouble code for secondary air injection?
Other secondary air injection system trouble codes include P0411, P0412, P0413, P0414, P0415, P0416, P0417, P0418, P0419, P041F, P044F, P0491, and P0492. Possibly symptoms include: A code P0410 may mean that one or more of the following has happened: Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
What are the symptoms of a bad mass air flow sensor?
Some of the most common symptoms of a bad Mass Air Flow sensor in Mercedes Benz cars are: Engine dies, stalls soon after you start it. Engine hesitates when you accelerate. Poor throttle response. Engine hiccups. Engine displays unusually lean or rich idling.
The set-up in question is called the ‘secondary air injection’ system, which pumps air into the engine’s exhaust system when it is cold. The oxygen contained in this air allows the remaining fuel in the exhaust gases to combust, helping reduce emissions and warm up the catalytic converter. How does secondary air injection work?
What happens when a secondary air injection pump goes bad?
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. One minute the power may be fine, and the next the RPM drop too much and the engine shuts off.
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.
How is secondary air supplied in an exhaust system?
The secondary air can be supplied actively or passively. In the passive system, fluctuations in pressure in the exhaust system are utilised. Additional air is drawn in via a timed valve due to the vacuum created through the flow speed in the exhaust pipe. In an active system, the secondary air is blown in by a pump.
What does secondary air injection system malfunction mean?
Error Code P0410 – Secondary Air Injection System Malfunction. Error Code P0410 is described as Secondary Air Injection System Malfunction. This means there’s an issue in the vehicle’s emission system, and can be caused by either electrical or mechanical failure.
When was secondary air injection introduced in cars?
(October 2015) ( Learn how and when to remove this template message) Secondary air injection (commonly known as air injection) is a vehicle emissions control strategy introduced in 1966, wherein fresh air is injected into the exhaust stream to allow for a fuller secondary combustion of exhaust gases.
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 an aspirated air injection system work?
Aspirated air injection. Air injection can also be achieved by taking advantage of the negative pressure pulses in the exhaust system at engine idle. 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.
The secondary air injection system helps reduce harmful pollutant emitted from the exhaust by pumping fresh air into the exhaust system. The PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) receives information from the secondary air injection system regarding the flow of the pressure.
What is the diagnostic code for secondary air injection?
P2441 is a diagnostic trouble code (DTC) for “Secondary Air Injection System Switching Valve Stuck Closed Bank 1”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What causes an air injection valve to get stuck?
The air injection system can get water or moisture in it. The pump flows the air and moisture into the valves, then the truck sits and the moisture rusts the valve stuck. There are all updated parts to put in.
What kind of problem is an air injection pump?
Defective air injection valve Defective air injection pump Defective one-way check valve Defective pressure sensor Broken, frayed or shorted pressure sensor wiring Broken, frayed or shorted vacuum switching valve wiring Broken, corroded, or melted vacuum switching connector Corroded or damaged pressure sensor connector

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.
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.
Cost of diagnosing the P0411 code. P0411 is a diagnostic trouble code (DTC) for “Secondary Air Injection System Incorrect Flow Detected”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
