Pressure Control Valve Inspection

WARNING: This page is about a different car, the 2013 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.

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.
Apply a pressure of 36 kPa {0.37 kgf/cm² , 5.2 psi} to port A.
Verify that there is airflow from port B.
- If there is no airflow, replace the pressure control valve assembly. (See FUEL TANK REMOVAL/INSTALLATION ).
