DTC P0443-13: Evaporative Emission System Purge Control Valve "A" Circuit Open [12/2019 - 10/2022]: Description
This DTC P0443-13 is applicable to Mexico models only.
To reduce hydrocarbon (HC) emissions, evaporated fuel from the fuel tank is routed through a charcoal canister to the intake manifold for combustion in the cylinders.
The ECM changes the duty signals to the purge VSV (Vacuum Switching Valve for Purge Control) so that the intake amount of hydrocarbon (HC) emissions is appropriate for the driving conditions (engine load, engine speed, vehicle speed, etc.) after the engine is warmed up.
