Code P0444 2012 Nissan Pathfinder Description

The P0444 code in a 2012 Nissan Pathfinder indicates a problem with the EVAP (Evaporative Emission Control) system, specifically with the Canister Purge Volume Control Solenoid Valve circuit being open. The EVAP system is responsible for capturing and storing fuel vapors from the fuel tank to prevent them from being released into the atmosphere. The Canister Purge Volume Control Solenoid Valve is a crucial component of this system, as it controls the flow of fuel vapor from the charcoal canister to the engine intake manifold for combustion.
