EGR Control Solenoid Valve (California)

  1. Label and disconnect vacuum hoses and wiring harness from solenoid valve. For solenoid valve location, see EGR CONTROL SOLENOID VALVE LOCATION  table.
  2. Connect hand vacuum pump to vacuum nipple where Green striped vacuum hose was connected. Apply vacuum and ensure vacuum does not hold. Apply battery voltage to one terminal of solenoid, and ground other. Ensure vacuum holds.
  3. Using an ohmmeter, measure resistance between terminals of solenoid valve. At room temperature, reading should be 36-44 ohms. Replace solenoid if not to specification.
