What is the diagnostic code for secondary air injection?
P0410 is a diagnostic trouble code (DTC) for “Secondary Air Injection System Malfunction”.
When does the p0410 O2 sensor fail?
Code P0410 is triggered when the air injection pump passive test fails or is inconclusive then the ECM commands the pump to do an active test and the O2 sensor does not output a higher O2 content in the exhaust within 3 seconds. Need help with a P0410 code?
How to check the O2 sensor PID on a scanner?
Monitors the O2 sensor pid on a scanner to see if the sensor reacts when the air injection pump is activated, the sensor should go to below 150 mv within 3 seconds Checks the air injection pump for proper resistance between pins of power and ground
How does a mechanic diagnose the p0410 OBD-II trouble code?
The Check Engine Light will be illuminated and the code is set in ECM memory and freeze frame. The air injection system pump may be noisy from bad bearings. The engine may run too rich if excessive O2 is being pumped into the exhaust. How does a mechanic diagnose the P0410 code?
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.

What are the symptoms of the air injection system trouble code?
The air injection system air intake is blocked causing low airflow into the exhaust. The O2 sensors are getting slow to respond to the increase in O2 in the exhaust. The catalyst is partly clogged increasing back pressure in the exhaust. The air injection pump relay contacts not making contact. What are the symptoms of the P0410 code?
How does the secondary air injection system work?
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 causes an air injection pump to fail?
The air injection pump system is to help lower the emissions coming out the exhaust and can cause the vehicle to fail emission testing. The check engine light being on causes the vehicle to fail emission testing. The air injection pump should not cause any drive symptoms other than a Check Engine Light.
What is the DTC for secondary air injection?
P0410 is a diagnostic trouble code (DTC) for “Secondary Air Injection System Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $70.00.

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?
The air injection pump relay contacts, not making contact. So, a faulty pump is generally the most frequent cause, of the system failing. Also, too much moisture can cause damage which results in, seizure of the pump. Finally, a faulty ground and voltage supply, can also cause the pump to fail.
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 injection smog pump go?
Consequently, inside the exhaust manifold, there is sufficient heat, to support combustion. 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.
P2431 is a diagnostic trouble code (DTC) for “Secondary Air Injection System Air Flow / Pressure Sensor Circuit Range / Performance 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.
The secondary air injection system is used to add air into the exhaust to reduce vehicle emissions. When the the incorrect flow is detected, the electronic control unit (ECU) detects this fault and sets the P2431 code. This code causes the Check Engine Light to be illuminated on the dashboard.
What does the p2431 code on the ECU mean?
What the P2431 code means. The secondary air injection system is used to add air into the exhaust to reduce vehicle emissions. When the the incorrect flow is detected, the electronic control unit (ECU) detects this fault and sets the P2431 code.
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.
How to test secondary air injection low flow?
Tests/Procedures: 1. This system uses a pressure sensor to monitor secondary Air Flow from the AIR Pump. At the secondary air sensor there is a 4 pin connector that will have 3 wires. The Brown wire is sensor ground at pin 1. Pin 3 is the 5 volt reference and pin 4 is the sensor signal to the ECM. 2.
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.
How much does it cost to diagnose a p0411 code?
The cost to diagnose the P0411 code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour. How much do you know about cars? When is the code detected?

How to get rid of an error code on an air pump?
To get rid of this error code, you can do the following: 1 Replace both the air pumps and the one-way check valve 2 Try and clean the air pump and test it. The one-way air check valve must be replaced as well 3 Replace the inlet hose of the air pump 4 Replace the fuse of the air pump (you can find it under the hood)

What should front O2 voltage be on SAS air pump?
As soon as the AIR pump kicks in, the front O2 sensor (s) voltage should be less than .125V (or 125 milivolts). If this code does not appear, then that’s a tell-tale sign for a fault condition in the SAS. If you DON’T hear the air pump motor start – Inspect the SAS Air Pump and relay.

When to use an electric pump for secondary air injection?
Nearly all modern secondary air injection systems use an electric pump rather than a belt-driven pump. Often, this setup is only used when the engine is cold to reduce emissions and bring the catalytic converter up to operating temperature quickly. The PCM monitors the secondary air injection system for faults.
What is the p0411 code for secondary air injection?
The PCM monitors the secondary air injection system for faults. If it detects a problem, it turns on the check engine light and triggers a P0411 code. It’s worth noting that not all vehicles have a secondary air injection system. Users have reported P0411 for the following makes: Volkswagen (especially on a VW Jetta), Chevrolet, BMW, GMC, and Audi.

What is the secondary air injection switching valve?
The Secondary Air Injection System (AIR) Switching Valve is the computer controlled valve that controls the air injection into the exhaust system of the engine (this valve may be integral to the AIR pump).
What causes a p0412 secondary air injection system code?

Is there bypass kit for secondary air pump?
The bypass kit can prevent many of the trouble codes caused by a mechanical failure of the secondary air pump or a secondary air valve saving you as much as a $2000-$4000 on a repair bill, turn off your CEL and keep the vehicle out of limp mode.
What does it mean if your air conditioner expansion valve is broken?
Thus, fixing the expansion valve as soon as possible will save you a lot of money in the long run. It’s not unusual for air conditioners to make noise when parts malfunction. As such, a broken expansion valve will cause your machine to make squealing, banging, or clanging noises that worsen over time.
How to troubleshoot an air brake system leak?
Check air valves for leaks at exhaust ports. Check lines for cracks or leaks at fittings. Check discharge line tor restrictions and carbon build-up. Clean or replace line as necessary.
