DTC P0443: Evaporative Emission Control System Purge Control Valve Circuit [03/2019 - 11/2022]: Description
WARNING: This page is about a different car, the 2022 Toyota Corolla, 2021 Toyota Corolla, 2020 Toyota Corolla, and 2019 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
HINT:
This DTC P0443 is applicable to models for Mexico 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.
