Code P0444 2002 Nissan Sentra Description
The P0444 code on a 2002 Nissan Sentra 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 vapors from the EVAP canister to the engine intake manifold. When the circuit is open, it means that there is an electrical issue preventing the valve from functioning properly. This can lead to increased emissions, decreased fuel efficiency, and potentially even engine performance issues.
