So I think I’m fundamentally missing something with the evap system in my 06. It seems like the evap purge solenoid on the engine is constantly open when the engine is running. I was under the impression that the solenoid only opens when it is venting the tank and not during constant operation? Or am I misunderstanding it’s purpose? I know there are 2 solenoids, one on the engine and one in the back of the car.
