EGR Valve

  1. Remove EGR valve from engine and inspect it for damage. Apply vacuum to EGR valve and watch diaphragm movement.
  2. Diaphragm should move to full open position and should remain in this position for at least 30 seconds after vacuum is shut off.
  3. Before reinstalling EGR valve, clean mating surface with a wire brush and compressed air. Remove foreign material from around valve and port.
