Question on operation of EVAP Canister Purge valve/Solenoid
The purge valve/solenoid on top of the Charcoal canister is in the closed position when fed voltage. Its not clanging open/closed like the vent solenoid at the valve cover.
If you apply and remove voltage (plug/unplug connector) the valve opens and closes as its supposed to.
Why is it not opening and closing as normal. Is the PCM sending it a signal to remain closed. Or is the valve gone bad.
In the closed position, its pulling vacuum on my gas tank.
