EGR Valve

  1. Disconnect EGR vacuum hose and attach a hand-held vacuum pump to vacuum hose port. Apply approximately 8 in. Hg to EGR valve while checking for smooth operation of diaphragm. Ensure diaphragm maintains position without losing vacuum.
  2. With engine at idle, apply vacuum to EGR diaphragm. Engine should idle rough and/or stall. If diaphragm retracts and engine RPM does not change, remove EGR valve and check for clogged passages.
