The Chevrolet Silverado Canister Purge Valves allow the truck to be cleaner and more efficient by controlling the flow of fuel vapor. It routes gasoline vapors from the charcoal canister to the engine, where they are burnt off instead of being let out into the air. The Canister Purge Valves are located between the canister packed with activated charcoal and the intake manifold, which opens as engine vacuum draws in clean air through the canister so that stored hydrocarbons mix with the air fuel charge. Early Silverado Canister Purge Valves applied relatively simple vacuum signals to operate. They opened when manifold pressure dropped. By contrast, modern OBD II Canister Purge Valves are electrically operated solenoids, which the engine computer controls. The engine computer can seal the system during self tests using a fuel tank pressure sensor to look for leaks. When Canister Purge Valves do not reach the target vacuum, a light will illuminate on the dashboard. It is likely a loose fuel cap, not a serious fault. The upgraded design applied in later Chevrolet models and in every current Silverado helps meet emission rules without sacrificing performance of Chevrolet engines.
