Leak Detection Solenoid: Testing and Inspection

EVAPORATIVE EMISSION VENTILATION SOLENOID CHECK




1. Connect a hand vacuum pump to nipple (A) of the evaporative emission canister and evaporative emission ventilation solenoid assembly.

2. Connect a plug to nipple (B) of the evaporative emission canister and evaporative emission ventilation solenoid assembly.







3. Check air tightness by applying a vacuum with voltage applied directly from the battery to the evaporative emission ventilation solenoid and without applying voltage.




4. Measure the resistance between the terminals of the solenoid.

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