Q: What is the function of the evaporative emissions control system and Vapor Canister and how to check?
A: The evaporative emissions control system sucks in fuel vapors from the gas tank and fuel system and stores them in a charcoal canister. A common symptom of a fault in this system is a strong fuel odor. If such an odor is detected, inspect the charcoal canister located under the rear of the vehicle, above the rear suspension cross member, and check the canister and all hoses for damage and deterioration.
