Code P0445 2006 Nissan Pathfinder Description

The P0445 diagnostic trouble code (DTC) for a 2006 Nissan Pathfinder indicates a problem with the EVAP (Evaporative Emission Control System) Canister Purge Volume Control Solenoid Valve circuit being shorted. The EVAP system is responsible for capturing and storing fuel vapors to prevent them from escaping into the atmosphere. The Canister Purge Volume Control Solenoid Valve regulates the flow of fuel vapor from the charcoal canister to the engine intake manifold for combustion.
