This happens because the SAS System may not maintain idle speed when it fails, partially closing the throttle plate to maintain RPMs. Symptoms of a bad secondary air injection pump or SAS pump are an engine that stalls or runs rough when idling. If you’re experiencing any of these symptoms, it’s important to take your car in for a diagnostic test as soon as possible! The sooner you address the problem, the less damage it will do to your car’s engine and catalytic converter. This is because a bad air injection pump can’t provide the engine with enough oxygen to function at its best. You may also notice that your car doesn’t seem as powerful as it used to be. If your car is sluggish when you try to accelerate, it’s likely because of a failing secondary air injection pump. When this pump fails, it can’t provide enough oxygen to the catalytic converter, which causes the engine to stall or run very slowly. If your car has a low idle, it’s most likely due to a problem with the air pump. The problem could be anything from a faulty pump to an issue with the fuel injectors themselves, so it’s important for any mechanic who works on cars regularly should know about this symptom! 4. It does this by oxidizing carbon monoxide, hydrocarbons, and nitrogen oxides with oxygen from the air injection system before they can enter your exhaust stream or cause an explosion in your garage! When there isn’t enough injected oxygen to do its job properly, these gases remain in higher concentrations than normal.Ī failed emissions test signifies that something isn’t right with your air injection system. The car’s catalytic converter converts harmful gases into less harmful ones. When your air injection smog pump fails, the emissions test will fail. If you’re experiencing any of these problems, it’s best to take your car in for a diagnostic test of tailpipe emissions to see if the catalytic converter is at fault. When the catalytic converter is not working properly, you will notice a decrease in fuel efficiency because of increased exhaust flow resistance, which increases engine operating temperatures. The air injection system helps keep it clean by injecting oxygen into the exhaust stream, which helps get rid of carbon monoxide and other pollutants before they can enter your car’s cabin or cause an explosion in your garage! The catalytic converter is the engine’s first line of defense against harmful emissions. This problem can lead to a loss in power and performance from your engine. If your secondary air injection pump has failed, you may notice that the catalytic converter is not working as well as it should. Failing to address the problem could result in more severe damage to your car. If your car has this light on, take it to a mechanic as soon as possible to have it checked out. This light comes on when there is a problem with the engine, and it can be triggered by a variety of issues, including a failing secondary air injection pump. One of the most common symptoms of a bad secondary air system is that the Check Engine Light will come on. Let us look at the signs of a bad air injection smog pump. Symptoms of Bad Secondary Air Injection Systemįollowing are the most common symptoms of a bad secondary air system. I know this sounds like a lot of work, but don’t worry – most cars today have these pumps as standard equipment, so it’s not something you’ll need to worry about unless your vehicle is older than 1990 or if you drive an exotic car like a Ferrari. This also aids in preventing air pollution and allows for better fuel economy since fewer pollutants are being emitted from your exhaust manifold. This helps the catalytic converter to start working more effectively. This keeps car’s emission clean and healthy to run on roads. The water vapor in fresh air creates a foam-like substance in the exhaust manifold, which grabs all the bad pollutants and takes them away from the catalytic converter. This system aims to inject oxygen into your exhaust stream during cold starts and at low speeds. This process helps reduce nitrogen oxide emissions harmful to human health and contributes to global warming. It mixes it with fuel that comes out of the engine before entering the internal combustion engine, where the combustion process occurs at high temperatures over 500 degrees Fahrenheit (260 C). It takes in ambient air from the atmosphere. The Secondary Air Injection Pump is a small device located on or near your car’s exhaust system. What is the Function of Secondary Air Injection Pump?
