            a digital meter [A] to the purge valve terminals

    Purge Valve Resistance
      Standard: 30  34 Ω @20°C (68°F)
    If the resistance reading is out of the specified value, re-
    place it with a new one.

• Connect the 12 V battery [A] to the purge valve terminals
  as shown.

• Blow  the air to the intake air duct [A], and make sure that
