EGR Control Solenoid Valve

  1. Label and disconnect vacuum hoses and wiring harness from solenoid valve. Connect a hand-held vacuum pump to vacuum nipple where Red or Green-striped vacuum hose was connected, and apply vacuum.
  2. While applying battery voltage to one terminal and grounding the other, ensure vacuum holds. Ensure vacuum is released when battery voltage is discontinued.
  3. Using an ohmmeter, measure resistance between solenoid valve terminals. Resistance should be 36-44 ohms at 68°F (20°C). Replace solenoid if resistance is not within specification.
