Q: What is the function and maintenance procedure for the Evaporative Emissions Control (EVAP) system,Canister Purge Valve and Vapor Canister in Honda Crosstour?
A: The EVAP system prevents fuel vapors from escaping into the atmosphere. It comprises the EVAP canister, canister vent shut valve, and fuel tank pressure sensor. Fuel odors indicate potential issues with the fuel filler cap, hoses, or canister. When replacing components, the purge valve is near the cylinder head or intake manifold. The canister is beneath the vehicle and requires removal of its cover, hoses, connectors, and bolts. The fuel tank pressure sensor and vent shut valve should be transferred from the old canister. Upon reinstallation, new O-rings are necessary.
