EVAP: The Evaporative Emissions Control system, or EVAP, plays a crucial role in curbing hydrocarbon pollution from gasoline-powered vehicles. While we often focus on tailpipe emissions, the EVAP system targets the constant release of gasoline vapors from the fuel tank and engine. Even when the engine is off, an open fuel system can contribute to pollution. Since the 1970s, EVAP systems have been mandatory on gasoline vehicles.

A standard EVAP system comprises a fuel tank, charcoal-filled vapor storage canister, valves, hoses, and a sealed fuel tank gas cap. Its purpose is to prevent fuel system fumes from escaping into the atmosphere. Vent lines direct vapors to the vapor canister, where they're stored until the engine starts. Once the engine warms up, a purge valve opens, allowing vapors to be drawn into the intake manifold and burned alongside the air/fuel mixture.

EVAP systems are low-maintenance but critical for emissions control. On pre-OBD II vehicles, issues were often only addressed when they caused performance problems, not emissions concerns. OBD II-equipped vehicles, however, have a PCM that monitors the system, ensuring no hydrocarbons escape. The PCM runs an EVAP diagnostic monitor under specific conditions, detecting even tiny leaks and triggering a Check Engine light if needed.
The tank stores fuel and is designed to be airtight. Failures at the tank's lower portions result in visible fuel leaks, while failures on top allow gasoline fumes to escape.

Understanding these components sheds light on the importance of the EVAP system in maintaining environmental standards for vehicle emissions.

*SOLUTION:* The issue can be caused by clogged or faulty EVAP Purge Valve / evap purge solenoid

Signs of a bad EVAP purge valve can be next:

-Check Engine Light
-Difficult Engine Starting
-Performance issues
-Rough Idling
-Poor Gas Mileage
-Failed Emissions Test
-Fuel Smell from the Engine
