Leak Detection Solenoid: Testing and Inspection
INSPECTIONEVAPORATIVE 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)]
