p0441 keeps poping up

Question

This has been going on for a while. Already replaced purge valve solenoid, and air filter. Where should I go from there?
On another note I thought it might be a electrical issue so I tested the voltage running to the purge valve solenoid and it came up with low voltage  (0.06) I also tested almost every wire the is connected to the evap system and the same thing happens. Is this normal? Do I need to have the car turned on in order for voltage to show up?

Answer 1

When you test for voltage the purge solenoid has to be commanded on, this is the state of no being turned on. Test the purge solenoid, you can remove it , blow through it in one direction and there should be no flow in either direction, if there is , the solenoid is non operational.
