When I put a vacuum on the solenoid valve today, out of the car with power (12V), to close it. I hear the vacuum leaking around the electrical plug.
When the car's computer runs the leak test, it close the vent solenoid valve and puts vacuum to the system and sees how long it take the vacuum to decay. To short in time it would throw a po 455 code.
So I'm thinking the vent solenoid it bad.
