Leak Detection Solenoid: Testing and Inspection

EVAPORATIVE EMISSION VENTILATION SOLENOID CHECK
1. Connect a hand vacuum pump to nipple (A) of the solenoid.




2. Check air tightness by applying a vacuum with voltage applied directly from the battery to the evaporative emission ventilation solenoid and without applying voltage.
3. Measure the resistance between the terminals of the solenoid.

Standard value: 17 - 21 ohms [at 20°C (68°F)]

4. Replace the solenoid if the resistance is out of specification.
