My m20b25 purge valve behaves in the following way:
With No power the valve allows flow from canister side to engine side but not from engine side to canister side
With power applied the valve does not allow flow either direction.
Thus it’s a normally open valve (one way at least...)
Is this correct? Couldn’t find relevant info in the Bentley. Wiring diagram doesn’t tell me when that circuit is powered. Im assuming it’s powered (closed) all the time except purge conditions.
