Code P0443 2006 Nissan Maxima Description

The P0443 diagnostic trouble code (DTC) for a 2006 Nissan Maxima refers to an issue with the EVAP Canister Purge Volume Control Solenoid Valve. The EVAP system is designed to capture and store fuel vapors from the fuel tank to prevent them from escaping into the atmosphere. The Canister Purge Valve controls the flow of these vapors from the charcoal canister to the engine intake manifold for combustion. The solenoid valve in question regulates the flow of the vapors, and a malfunction can lead to various issues.
