The egr valve is usually located on the intake manifold or head. There is a diaphram in the egr valve. The valve uses manifold vacuum on the diaphram to lift or close a valve allowing exhaust gas to enter the intake manifold. An easy test for the diaphram is to remove the vacuum line that runs to the egr valve.You can normally reach the diaphram area with your finger.here is a diaphram in the egr valve.

Save. In the early 1970s, automobile manufacturers began equipping their vehicles with EGR (exhaust gas recirculation) valves to reduce the levels of pollutants created by their vehicles. At high temperatures, oxygen and nitrogen combine to form nitrogen oxide, which is considered one of the main components of smog. EGR valves help to reduce the amount of nitrogen oxide produced by automobile engines by lowering the temperature of the combustion process in an engine.
