P0444 2011 Nissan Pathfinder Code - EVAP Canister Purge Volume Control Solenoid Valve Circuit Open

Quick Answer

The P0444 code on a 2011 Nissan Pathfinder indicates a problem with the EVAP (Evaporative Emission Control) system, specifically with the Canister Purge Volume Control Solenoid Valve circuit being open. Common causes include Faulty Canister Purge Volume Control Solenoid Valve: The valve itself may be defective and unable to open or close properly, Damaged Wiring: Corrosion, fraying, or breaks in the wiring connected to the solenoid valve can disrupt the electrical signal, Blown Fuse: A blown fuse in the EVAP system circuit can prevent the Canister Purge Volume Control 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 2011 Nissan Pathfinder Description

The P0444 code on a 2011 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 to prevent them from escaping into the atmosphere. The Canister Purge Volume Control Solenoid Valve is a crucial component of this system, as it regulates the flow of fuel vapor from the charcoal canister to the engine for combustion.
