Q: What is the Fuel Vapor Canister System,Canister Purge Valve and Vapor Canister?
A: This system traps and stores fuel vapors. It consists of a charcoal-filled canister, purge solenoid, relief valve, and connecting lines. When the engine is off, the charcoal absorbs the vapor, and when it's on, the vapor is routed to the intake manifold. The canister is purged using engine vacuum, and the relief valve vents the fuel tank. Inspect for damage and test the canister and solenoid. The canister is located behind the headlight, and the solenoid is on the firewall or fender well.
