Code P1446 2004 Infiniti G35 Description
The P1446 code on a 2004 Infiniti G35 refers to an issue with the EVAP (Evaporative Emission Control) system, specifically the Canister Vent Control Valve. This valve is responsible for controlling the flow of fuel vapors from the fuel tank to the charcoal canister. When the engine is running, the EVAP system seals the fuel tank and prevents harmful vapors from escaping into the atmosphere. The Canister Vent Control Valve opens and closes to allow the fuel vapors to be purged into the engine and burned.
