Purge Control Solenoid Valve

  1. Disconnect Red-striped vacuum hose from purge control solenoid valve and detach harness connector. Connect vacuum pump to nipple where Red-striped vacuum hose was removed. Apply vacuum and battery voltage to valve. With battery voltage applied, vacuum should release. With battery voltage disconnected, vacuum should hold.
  2. Using an ohmmeter, measure resistance between solenoid valve terminals. At 68°F (20°C), resistance should be 36-44 ohms.
