Refueling Control Valve: Testing and Inspection
ORVR VENT VALVE MODULE CHECK1. Blow air through orvr vent valve module nipple (A). Check that the air flows out of nipple (B) and nipple (C).
2. Connect a hand vacuum pump to nipple (A) of the over vent valve module.
3. With air flow through nipple (C) obstructed apply a vacuum and check that the vacuum is maintained.
4. Check air tightness by applying a vacuum with voltage applied directly from the battery to the over vent valve module and without applying voltage.
5. Measure the resistance between the terminals of the solenoid.
Standard value: 17 - 21 Ohms [at 20 °C (68 °F)]
6. Replace over vent valve module if resistance is out of specification.
