How does the fuel canister purge system work?
Modern vehicles are equipped with an EVAP system that works to reduce the evaporative emissions pollution that can come from the vehicle’s fuel tank, which is released in the form of vapors. The EVAP system traps this vapor in a charcoal canister and recirculates it for use as fuel for the engine and prevented from polluting the environment.
What does the canister purge solenoid do in a charcoal engine?
The EVAP system traps this vapor in a charcoal canister and recirculates it for use as fuel for the engine and prevented from polluting the environment. The canister purge solenoid — also referred to as an EVAP canister valve — is responsible for “purging” the EVAP system by acting as the switch that allows the vapor into the engine.

What causes a purge valve to set code p0443?
The cause of code P0443 can be a purge control valve internal open circuit or the connector is corroded causing loss of contact with the valve. The code can also be set if the wiring to the valve is damaged between the ECM and the purge valve causing an open circuit if the wire is cut or a short if the wire is shorted to ground or a power source.
