  1. Looking through opening in EGR valve body, check that valve shaft moves when engine reaches 3000-3500 RPM under no-load condition.
  2. If shaft does not move as specified, remove valve and manually check valve movement. If valve appears okay, check vacuum lines for leaks.
  3. If valve does not operate, clean or replace. Check EGR pipe for deposits or clogging.
