Evaporative Emission Control Canister: Testing and Inspection

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 solenoid if resistance is out of specification.
