DTC P0444 Or DTC P0445: Description

WARNING: This page is about a different car, the 2002 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

The EVAP Canister Purge Volume Control Solenoid Valve (EVAP-CPVCSV) uses an ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP-CPVCSV is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.
