Check engine light code po446.
Replaced vent solenoid, coil was bad.
Light stays off but after restart it's back on.
Checked the purge solenoid valve, ground was bad so i ran a new ground wire.
Light still comes on.
With key on should the front purge valve be open?
From what I can understand the front valve open when you start and the rear valve closes.
Is this correct? Checked all lines for leaks and still cannot correct this problem.

Thanks for any help.
