![]() ![]() Secondary Air System Is Not Ready? How Can I Check IT? As a result, hydrocarbons may not be completely burned, and emissions may increase. When this happens, it means that the system is not injecting enough air into the exhaust stream. Secondary air injection systems can sometimes malfunction, causing the “check engine” light to come on. In a passive system, atmospheric pressure is used to draw air into the stream. In an active system, a pump forces air into the exhaust stream. There are two types of secondary air injection systems: active and passive. This helps to reduce emissions of harmful pollutants from the vehicle’s engine. Its purpose is to inject fresh air into the exhaust stream, in order to promote more complete combustion of any unburned hydrocarbons in the exhaust gas. How Does a Secondary Air System Work?Ī secondary air system is a component of some vehicles’ exhaust systems. ![]() The secondary air system is required by law in many jurisdictions, as it helps to reduce emissions of harmful pollutants such as carbon monoxide, hydrocarbons, and oxides of nitrogen. The air pump is usually powered by the engine’s electric system. The secondary air system consists of an air pump, one or more valves, and a series of hoses and pipes that deliver the fresh air to the exhaust system. This fresh air helps to complete the combustion process and reduce emissions. The purpose of the secondary air system is to introduce fresh air into the exhaust system of a vehicle with an internal combustion engine. The air part is where the secondary air system comes in. Other potential reasons include a problem with the oxygen sensors, air pump, or other components of the secondary air system.Īn internal combustion engine needs three things in order to function: air, fuel, and ignition.If the car has recently had its battery replaced or disconnected, this can also cause the system to reset and become “not ready.”.The car needs to be driven for a certain amount of time (usually around 50 miles) before the system will be considered “ready. The most common reason is that the OBDII system has not had enough time to run its self-diagnostics.Assuming the system is throwing the “Not Ready” code, it could be for a number of reasons. ![]()
