Understanding Your Car’s EVAP System
The EVAP system is designed to prevent harmful fuel vapors from escaping into the atmosphere. It captures these vapors and stores them in a charcoal canister, later purging them into the engine for combustion. A complex network of components, including the fuel tank, vent control valve, purge valve, and various hoses and sensors, work together to ensure this process runs smoothly.
Common Car Evap Problems
Several issues can disrupt the EVAP system, often leading to that annoying check engine light. Loose or damaged gas caps are a frequent culprit, as they break the airtight seal necessary for proper vapor capture. Other common problems include faulty vent control valves, cracked or disconnected hoses, and a malfunctioning purge valve. Occasionally, the charcoal canister itself can become saturated and require replacement.
Diagnosing Car Evap Problems
Diagnosing car evap problems can range from simple visual inspections to more complex diagnostic tests.
