What Does a Vapor Canister Do?

The vapor canister is a critical component of the EVAP system. It stores harmful fuel vapors produced by the fuel tank, preventing them from escaping into the atmosphere. When the engine is running and conditions are met, the purge valve opens and stored vapors are drawn into the engine to be burned as part of the normal combustion process, reducing harmful hydrocarbon (HC) emissions.

• Illuminated Check Engine Light (CEL) with EVAP-related trouble codes
