Pressure Control Valve Inspection

  1. Remove the pressure control valve assembly. (See FUEL TANK REMOVAL/INSTALLATION .)
    CAUTION:
    • Do not apply a pressure 36 kPa {0.37 kgf/cm2, 5.2 psi} or more. Doing so will damage the pressure control valve and evaporative hose.
  2. Apply a pressure of 36 kPa {0.37 kgf/cm2 , 5.2 psi} to port A.
  3. Verify that there is airflow from port B.
    • If there is no airflow, replace the pressure control valve assembly. (See FUEL TANK REMOVAL/INSTALLATION .)
