What is the EVAP System?

The Evaporative Emission Control (EVAP) system prevents fuel vapors from escaping into the atmosphere. Key components include:

  • Charcoal Canister - Stores fuel vapors from tank
  • Purge Valve - Controls vapor flow to engine
  • Vent Valve - Allows fresh air into system
  • Fuel Tank Pressure Sensor - Monitors system pressure
  • Hoses and Lines - Connect all components

Common EVAP System Problems

  • Check engine light with EVAP codes (P0440-P0499)
  • Failed emissions inspection
  • Strong fuel smell near vehicle
  • Difficulty filling gas tank
  • Gas cap warning light
  • Poor fuel economy
  • Rough idle or stalling

Most Common EVAP Codes

  • P0440 - EVAP system malfunction
  • P0441 - EVAP system incorrect purge flow
  • P0442 - EVAP system leak detected (small)
