NOTE: When disconnecting the vacuum hose, place an identification
mark on it for proper re-connection.

1. Disconnect the vacuum hose from the solenoid valve.




2. Disconnect the harness connector.




3. Connect a hand vacuum pump to nipple (A) of the solenoid valve.




4. Check air tightness by applying a vacuum with voltage applied directly from the battery to the purge control solenoid valve.




5. Measure the resistance between the terminals of the solenoid valve.
Standard value: 27 - 37 Ohms [at 20° C (68° F)]
