While a faulty purge valve may not cause immediate catastrophic damage, it can:

Damage the Fuel Tank: If the valve stays closed, fuel vapor pressure can build up, potentially damaging the fuel tank.
Affect Engine Performance: Prolonged issues can lead to decreased performance, rough idling, and poor fuel economy.
Catalytic Converter Risk: Poor vapor management can cause unburned fuel to reach the catalytic converter, potentially damaging it over time.

It’s best to replace the purge valve sooner rather than later to prevent long-term engine and emissions system damage.
