DTC P0443: Evaporative Emission Control System Purge Control Valve Circuit: Description
WARNING: This page is about a different car, the 2010 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
HINT:
This DTC P0443 is applicable to Mexico models only.
To reduce HC emissions, evaporated fuel from the fuel tank is routed through the charcoal canister to the intake manifold for combustion in the cylinders.
The ECM changes the duty signal to the VSV for EVAP so that the intake quantity of HC emissions is appropriate for the driving conditions (engine load, engine speed, vehicle speed, etc.) after the engine is warmed up.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0443 | Terminal voltage of ECM output circuit does not correspond with drive signal from ECM to purge VSV (1 trip detection logic) |
