EGR Valve

  1. Ensure engine is at normal operating temperature. Disconnect EGR valve vacuum hose, and connect a vacuum pump to EGR valve. Start engine. Apply at least 6 in. Hg to EGR valve.
  2. If engine stalls and gauge holds vacuum, EGR valve is functioning properly. Connect a vacuum gauge to EGR hose. Increase engine speed to about 3000 RPM. If vacuum is shown on gauge, system is functioning properly.
