Code P0443 Chrysler Description

The Evaporative Emission System (EVAP) canister purge volume control solenoid valve uses an ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the Engine Control Module (ECM). The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve. The Diagnostic Trouble Code (DTC) will be set when an improper voltage signal is sent to Engine Control Module through the valve.
