This valve basically regulates the pressure within the Exhaust Gas Recirculation system. It doesn’t make the EGR happen, but it ensures the system works properly. Think of it like a regulator on a propane tank – it keeps things at a safe and effective level. It opens and closes based on engine conditions, allowing the right amount of exhaust gas to be recirculated back into the intake. It’s a pretty simple part mechanically, but crucial for a bigger system to function. The EGR system, and this valve as a part of it, is designed to reduce emissions and improve fuel economy. It recirculates a portion of exhaust gas back into the engine's intake manifold. This lowers combustion temperatures, reducing the formation of nitrogen oxides, which are harmful pollutants. It’s a key piece of your vehicle meeting emissions standards, and contributing to cleaner air. The valve itself is usually connected to the EGR cooler and the intake manifold with some vacuum lines, and it responds to signals from the engine control unit. If this valve fails, a bunch of things can happen. You might experience rough idling, misfires, a check engine light (of course), and a noticeable drop in fuel economy. Sometimes it'll cause the engine to run too rich or too lean. It can even cause the engine to stall. Essentially, it messes with the delicate balance of the engine’s air – fuel mixture. It’s not something you want to ignore. We carry a good selection of these at Fixparts Online, and getting a new one installed when needed can save you bigger problems down the road. You’ll notice if this thing starts failing, usually with some performance issues or that check engine light. Invest in reliability: Pressure Valve (MPN 059130789) includes a 12-month warranty!
