EGR Valve

What is EGR Valve, and what does it do?

An EGR valve is an emissions control device that recirculates metered amounts of spent exhaust gas back into the engine’s intake manifold. Re-burning this gas lowers combustion temperatures to reduce harmful nitrogen oxide emissions. Over time, heavy soot and carbon buildup can jam the valve open, causing black exhaust smoke, hesitation, and engine limp modes.

What are common signs of a problem with EGR Valve?

Common signs of a problem with an EGR valve include rough engine idling, sluggish throttle response, black exhaust smoke under acceleration, and reduced fuel economy. A valve stuck open or closed also triggers the check engine light, producing diagnostic trouble codes related to exhaust gas recirculation flow or intake manifold pressure.
