Code P0445 2010 Nissan Sentra Description

The P0445 diagnostic trouble code (DTC) for a 2010 Nissan Sentra indicates a problem with the EVAP (Evaporative Emission Control) system, specifically the Canister Purge Volume Control Solenoid Valve circuit being shorted. The EVAP system is designed to prevent fuel vapors from escaping into the atmosphere by capturing and storing them in a charcoal canister until they can be purged and burned in the engine. The Canister Purge Volume Control Solenoid Valve is responsible for controlling the flow of fuel vapor from the charcoal canister to the engine for combustion.
