EGR Modulator/EGR Pressure Transducer

  1. For EGR modulator/EGR pressure transducer location, see appropriate vacuum diagram in the VACUUM DIAGRAMS article. Remove upper cap from modulator/pressure transducer. Remove filter and clean with compressed air. Reinstall filter and upper cap. Remove EGR modulator/EGR pressure transducer.
  2. Using low air pressure, apply air to one vacuum hose port and plug opposite vacuum hose port. Air should flow freely through filter housing.
  3. Connect hand-held vacuum pump to one vacuum hose port. Connect vacuum gauge to opposite vacuum hose port. Using low air pressure, apply air to bottom port while applying vacuum with vacuum pump. Vacuum should be indicated on gauge. When low air pressure application stops at bottom port, vacuum gauge indicator should return to zero. Replace EGR modulator/EGR pressure transducer if operation is not as specified.
