Dust & Humidity: In places like Karachi and Lahore, the high levels of dust and humidity can cause dirt and moisture to enter the EVAP system, clogging o r damaging the purge control valve.
Fuel Quality: Low-quality o r contaminated fuel can lead to the accumulation of carbon deposits, which may clog the purge valve and prevent it from functioning correctly.
Extreme Temperatures: The hot climate can cause seals and internal components of the purge valve to degrade over time, leading to failure.
