Exhaust gas recirculation (EGR) is a system that takes exhaust gas from a dieselâs exhaust manifold and reintroduces it into the intake of the engine to reduce the combustion chamber temperature.
To test the EGR valve: Remove the vacuum line to the valve and install a manual vacuum pump. Start the engine and apply vacuum to the valve. If the engine idle speed drops, the EGR valve is working. If the engine idle speed does not change, the EGR system is not working.
