The secondary air injection system is an emissions system equipped on many road going vehicles. The air pump check valve is the valve that allows air supplied from the air pump to be pumped into the exhaust stream to reduce hydrocarbon and carbon monoxide tailpipe emissions.
The air injection smog pump pushes air into the exhaust system right after the exhaust manifold, to help intercept and burn those unburned fuels. The system is critical to help cars achieve government emissions standards.
Beside above, what is the purpose of secondary air pump? The purpose of the secondary air injection pump is to prevent hydrocarbons from getting into the environment. A lot of times the secondary air injection pump is called a smog pump for this reason. The smog pump is located right past the exhaust manifold allows air to be pumped into the exhaust.
Subsequently, one may also ask, what is a secondary air valve?
Secondary–air valves are fitted between the secondary–air pump and the exhaust manifold. Use is made of different versions. The secondary–air non-return valve stops exhaust gas, condensate or pressure peaks in the exhaust system (e.g. misfiring) causing damage to the secondary–air pump.
How much does it cost to fix a secondary air injection system?
All cars are required to have secondary air injection systems, which make exhaust emissions cleaner and help to combust more harmful gases. If your secondary air system fails, then replacing it will cost you between $270-$390. The labor should run you about $90, while parts cost, on average, about $250.
Can you drive with a bad air pump?
Many states also have strict emissions regulations for their road going vehicles, and any problems with the air pump or the air injection system can not only cause performance problems, but also cause the vehicle to fail an emissions test.
What is the purpose of an air pump on a car?
An air pump, also commonly referred to as a smog pump, is an emissions component that is part of the secondary air injection system. It is responsible for pumping clean air into the vehicle’s exhaust stream to promote a cleaner and more complete burn before the fumes exit the tailpipe.
What causes a secondary air injection system malfunction?
CAUSES OF A FAILURE: CAUSE OF FAILURE Faulty ground and voltage supply can also cause the pump to fail. Blocked or leaking lines can also cause the failure or malfunction of the control or combination valve, resulting in the failure of the secondary air system.
How long does the secondary air pump run?
What causes secondary air injection 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 does p0410 code mean?
P0410 is an OBD-II generic code that the engine control module (ECM) detected the engine O2 sensor did not detect an increase in the O2 level in the exhaust when the air injection system was commanded on during an active test.
How does a secondary air injection work?
Secondary air injection systems pump outside air into the exhaust stream so unburned fuel can be burned. Newer aspirated systems use the vacuum created by an exhaust pulse to pull air into the pipe. The latest systems use an electric motor to pump air. These systems are critical for the life of the catalytic converter.
How do I know if my secondary air pump is bad?
Top 5 Bad Secondary Air Injection Pump Symptoms 1) Check Engine Light. One of the early symptoms of a bad secondary air injection pump is the Check Engine warning light turning on. 2) Failed Emissions Test. 3) Weak Acceleration. 4) Engine Stalling. 5) Low Idle.
Where is secondary air pump?
The secondary air pump must draw in ambient air and inject it into the exhaust gas manifold downstream of the exhaust valves. If the air is drawn not from the intake area but directly from the engine compartment, a separate air filter is built into the secondary air pump.
How do you test the efficiency of a secondary air system?
To check the efficiency of a secondary AIR system, a system efficiency test is performed. When the air injection system is working properly, the emission of HC, CO, and CO2 are decreased, while O2 is increased.
What is secondary air system monitor?
Secondary AIR System Monitor. When vehicles are equipped, the secondary AIR system monitor allows the PCM to ensure that extra air is being delivered to the exhaust system during cold engine operating conditions. The monitor usually runs on the start up of a cold engine, conditions permitting.
