How Does a Bad Purge Control Valve Affect Emissions and the Environment?

How Does a Bad Purge Control Valve Affect Emissions and the Environment?

Since the purge valve is part of the Evaporative Emission Control System EVAP, how does a malfunction lead to higher emissions and environmental damage in cities like Lahore, where smog is a major issue?

A malfunctioning purge valve in a Toyota Camry directly affects the EVAP system, which is responsible for controlling fuel vapor emissions:

Higher Emissions: A stuck valve can allow excessive fuel vapor to escape into the atmosphere, increasing harmful emissions, especially in smog-prone areas like Lahore.
Environmental Impact: The release of unburned hydrocarbons contributes to pollution and environmental damage.
