Canister Purge Solenoid: Testing and Inspection

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 airtightness 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: 36-44 ohms at 20°C (68°F)
