Code P0445 2012 Nissan Pathfinder Description

The P0445 code for a 2012 Nissan Pathfinder indicates a problem with the EVAP (Evaporative Emission Control) system, specifically the Canister Purge Volume Control Solenoid Valve circuit being shorted. The EVAP system is designed to capture and store fuel vapors from the fuel tank to prevent them from escaping into the atmosphere. The Canister Purge Volume Control Solenoid Valve is responsible for controlling the flow of fuel vapors from the charcoal canister to the engine intake manifold for combustion.
