DTC P0447 EVAP Emission Control System Vent Circuit Open

DESCRIPTION
The evaporative system prevents hydrocarbon (HC) vapor escaping from the fuel tank into the atmosphere where they would form photochemical smog. Gasoline vapor is collected in the charcoal canister. The Canister Close Valve (CCV) closes off the air inlet to the canister for leak detection of the evaporative emission system. The CCV also prevents fuel vapors from escaping from the canister. When the engine purges HC vapor from canister, the clean air comes into the canister through canister air-filter and CCV.
