An evaporative (EVAP) leak refers to a leak in the vehicle’s evaporative emissions control system. This system is designed to capture and store fuel vapors from the fuel tank and prevent them from escaping into the atmosphere. When there is a leak in the system, it can cause issues such as the check engine light illuminating and potential problems with emissions testing.

Here’s an overview of the EVAP system and common causes of leaks:

  1. Components: The EVAP system includes components such as the charcoal canister, purge valve, vent valve, and various hoses and lines.
  2. Purpose: The system captures fuel vapors from the fuel tank and stores them in the charcoal canister. The vapors are later purged into the engine and burned off during normal operation.
  3. Common Causes of Leaks:
    • Loose or Damaged Gas Cap: A loose, cracked, or damaged gas cap can cause a leak in the EVAP system.
    • Cracked or Damaged Hoses: Hoses in the EVAP system can become cracked or damaged over time, leading to leaks.
    • Faulty Purge Valve: The purge valve controls the flow of vapors from the charcoal canister to the engine. A faulty purge valve can cause leaks or other issues.
    • Faulty Vent Valve: The vent valve allows fresh air to enter the charcoal canister to displace the vapors being drawn into the engine. A faulty vent valve can cause leaks or other issues.
  4. Diagnosis and Repair: To diagnose an EVAP leak, a technician may use a smoke machine to visually inspect the system for leaks. They may also use a scan tool to check for trouble codes related to the EVAP system. Once the leak is located, repairs may involve replacing hoses, valves, or the charcoal canister, depending on the issue.
  5. Clearing Codes: After repairing the EVAP leak, the trouble codes stored in the vehicle’s computer should be cleared using a scan tool. This will reset the check engine light and allow the vehicle to be retested if necessary.

If you suspect an EVAP leak in your vehicle, it’s best to have it diagnosed and repaired by a qualified technician to ensure proper functioning of the emissions control system.
