Evaporative Vapor Pressure Sensor: 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.
