Q: What is the function of the evaporative emissions control system and Vapor Canister and how to check?
A: First of all, the evaporative emissions control system's role is to store fuel vapors from the gas tank in a charcoal canister and route them to the intake manifold. A strong fuel odor in the engine compartment often indicates a fault in this system. If detected, inspect the charcoal canister and hose connections for cracks and damage. Check the canister and hoses for deterioration.
