  Q: What is the function of the evaporative emissions control system and Vapor Canister?

  A: The evaporative emissions control system draws fuel vapors from the gas tank, stores them in a charcoal canister, and routes them to the intake manifold. A common symptom of a fault in this system is a strong fuel odor. For 2002 and earlier models, this odor is usually detected in the engine compartment, while for 2003 and later models, it's detected from the rear of the vehicle. The charcoal canister's location varies depending on the model year. For 2002 and earlier, it's on the passenger's side firewall. For 2003-2006, it's near the right-rear wheel. For 2007 and later, it's under the vehicle. Always check the canister and hoses for damage.
