P0444 2009 Nissan Pathfinder Code - EVAP Canister Purge Volume Control Solenoid Valve Circuit Open

Quick Answer

The P0444 code on a 2009 Nissan Pathfinder indicates a problem with the EVAP (Evaporative Emission Control System) Canister Purge Volume Control Solenoid Valve circuit being open. Common causes include Faulty EVAP Canister Purge Volume Control Solenoid Valve: The solenoid valve itself may be malfunctioning and not allowing proper flow of fuel vapor, Damaged Wiring or Connectors: Any damage to the wiring or connectors in the circuit can interrupt the electrical connection, Blown Fuse: A blown fuse in the circuit can prevent the solenoid valve from receiving power. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P0444 2009 Nissan Pathfinder Description

The P0444 code on a 2009 Nissan Pathfinder indicates a problem with the EVAP (Evaporative Emission Control System) Canister Purge Volume Control Solenoid Valve circuit being open. This valve is responsible for controlling the flow of fuel vapor from the EVAP system to the engine intake manifold. When the circuit is open, it means that there is an interruption in the electrical connection between the solenoid valve and the vehicle's ECU (Engine Control Unit).
