The Vapor Canister in Cadillac CTS vehicles is located in the evaporative emissions control (EVAP) system which was developed to ensure evaporation rather than emission of hydrocarbons in the atmosphere. This component is also termed the carbon or charcoal canister and is used to store fuel vapours which come from the fuel tank. When the engine needs more fuel, these vapors are released by the canister through some which is then sucked along with air and transported directly into the engine to be burnt. Years of Cadillac CTS models have come with different styles of Vapor Canisters whereby some have filters that can be replaced in order to enhance efficiency. Existing Cadillac CTS cars have improved EVAP systems to include check devices like a canister vent solenoid and, fuel tank pressure sensor, for the identification of leaks and proper functioning. Such developments assist in preserving the high standards of the framework which in turn makes a contribution towards lowering of emissions and meeting environmental standards.
