Cleaning: In some cases, cleaning the valve with a solvent o r cleaner may restore its function temporarily, especially if it’s clogged with carbon deposits.
Replacement: If the valve is severely clogged, corroded, o r damaged, replacement is the best option for long-term reliability.

Lifespan: The purge valve typically lasts around 100,000 to 150,000 kilometers, but this can vary depending on driving conditions and environmental factors.
Preventive Maintenance:

Regular Inspection: Check the valve during routine maintenance, especially if you notice any idling o r fuel-related issues.
Fuel Quality: Use high-quality fuel to minimize carbon build-up in the EVAP system.
Air Filter & System Cleaning: Make sure your air filters are clean and your system is free of contaminants to extend the life of the purge valve.
