Toyota Prius Vapor Canister Parts Questions & Answers

• Q: What is the function of the evaporative emissions control system and Vapor Canister and how to check?

  A: The evaporative emissions control system functions to draw fuel vapors from the gas tank and fuel system, store them in a charcoal canister, and then burn them during normal engine operation. A common symptom of a fault in this system is a strong fuel odor from the rear of the vehicle. If a fuel odor is detected, an inspection of the charcoal canister duct is necessary. On all models, it is located on or above the fuel tank. The canister and all hoses should be checked for damage and deterioration.
