Anyone know if this DTC will go inactive and the check engine light will go out if the problem is fixed or is it a latching code and it needs to be cleared? I'd love to replace the purge valve assembly and drive the car until the light goes out to confirm that was the true problem or not. I've had the P1450 coming on intermittently for the past year or so now. I can normally just clear it out and it may not come back for a couple months or so...
