Although most people understand the importance of an EGR valve to proper engine performance, few people other than professional engineers truly understand exactly what it does. It seems a bit counter-intuitive, but it actually redirects a portion of the exhaust fumes back into the engine for further combustion. By doing so, the car produces cleaner emissions and the exhaust helps neutralize the buildup of flammable nitrogen oxide or other toxic gases in the combustion chamber.
The EGR valve isn’t going to physically break, but it can malfunction in one of three ways. It can either get stuck in the open position, it can get stuck in the closed position, or it can get clogged which is going to make it act as if it were closed.
Once it is stuck in a position and will no longer open or close, it needs to be replaced. If it’s clogged it can usually be cleaned, but the engine might need a further inspection to determine the cause for the filth. The best idea is to have cleaned, typically about every 50,000 miles for most vehicles, as that will make it last longer and lessen the likelihood of a more serious malfunction from occurring.
If the EGR valve is stuck in the open position, it allows too much of the exhaust back into the engine combustion compartment at inappropriate times, causing the engine to rev unexpectedly or stall at low speeds.
If it is stuck closed or clogged, it allows the buildup of gasses in the combustion area, which leads to erratic firing and explosions which can cause extensive damage to other components around the engine block and cylinders. Either situation will cause the engine to act strangely and showed a marked lack of performance both in acceleration and gas mileage.
The EGR valve can be a bit tricky to diagnose as the symptoms it causes when malfunctioning is the same as what many other system failures can cause.
