This part basically forces air into the exhaust system. It doesn’t run all the time, it's activated by the engine control unit – the computer in your car. What it does is open a valve on the exhaust side, and the pump blows air in there. It's a pretty simple device mechanically, but it plays a crucial role when the engine needs a little help. Think of it like this: sometimes the exhaust system gets clogged up a bit, or the engine isn’t running perfectly. The air pump steps in to help burn off any extra fuel that hasn’t been completely used. It’s most noticeable when you first start the car, or when the engine is running rich, meaning it's using too much fuel. It’s also a key part of your emissions system, helping to keep everything running clean and meeting those environmental standards. If this pump goes bad, you’ll likely see a check engine light come on. That light isn't always something huge, but it’s telling you something is off. You might also notice a rough idle, or even a decrease in fuel economy. Sometimes, it won’t be super obvious at first, but left unchecked, it can cause other parts of your exhaust system to work harder than they should. It's a relatively inexpensive part to replace, and keeping it in good shape can prevent more serious – and costly – repairs down the line. You can find replacements pretty easily; places like Fixparts Online usually have a good selection. Affordable and reliable: Air Pump (MPN 0580000025) has a 12-month warranty!
