WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

Blow air through ORVR vent valve module nipple (A). Check that the air flows out of nipple (B) and nipple (C).

Measure the resistance between the terminals of the solenoid.
Standard value: 17 - 21 Ω [at 20°C (68°F)]
Replace ORVR vent valve module if resistance is out of specification.
