WHERE DO I LOCATE THE EGR VALVE ON MY 2001 CHEVY IMPALA 3.8 V6

Sorry I misunderstood your question. I was thinking of the pcv valve. But now for you real question.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. Move this opposite from the direction it normally sits at. Then cover the vacuum port located on the egr valve with a plugged hose or your finger. The diaphram should either stay in this other position or slowly move to the normal position. If it won’t hold vacuum and instantly returns to it’s origional position, either a vacuum port is still not plugged or the diaphram is leaking. If it is leaking replace the egr valve. If the egr valve holds vacuum then remove the valve from the manifold.

there is no vacuum hose attached to the ERG valve, this is a 2001 Acura MDX. only an electrical plug in there is no vacuum hose attached to the ERG valve, this is a 2001 Acura MDX. only an electrical plug in
