P0443 on Kia
Evaporative Emission Control System Purge Control Valve Circuit
P0443 on Kia vehicles indicates evaporative emission control system purge control valve circuit. Au7o has documented this code across 1 Kia model — most commonly on Forte. This is an emissions (EVAP) code. The evaporative emission system captures gasoline vapors from the fuel tank and routes them to the engine to be burned, instead of letting them escape into the air; the purge control valve opens and closes to let those stored vapors into the intake at the right times. P0443 means the engine computer detected an electrical fault in the purge valve (purge solenoid) circuit — such as an open, short, or out-of-range signal. It generally won't affect how the car drives, but it will turn on the check engine light and can cause an emissions test failure. Typical repair costs on Kia range from $90 to $350, depending on the specific model and root cause.
Common Causes of P0443
- •Failed EVAP purge control valve/solenoid
- •Damaged wiring or corroded connector at the purge valve
- •Short to power or ground in the purge circuit
- •Open circuit or broken wire to the solenoid
- •Blown fuse or power-supply fault to the valve
- •Connector water intrusion or corrosion
- •Faulty engine control module driver (less common)
P0443 on Kia by Model
Kia Forte(1 issue)
- Canister Purge Control Solenoid Valve (PCSV) Sticking Open - Hard Start After Refueling and P0441/P04962010-2023
The EVAP purge control solenoid on the Forte's intake sticks or leaks in the open position, so fuel vapor from the charcoal canister is pulled into the intake manifold when it should be sealed - including with the engine off and immediately after a fill-up. The classic owner symptom is a car that cranks a long time or needs several attempts to start only right after filling the tank (the intake is flooded with vapor, giving an over-rich start), then runs fine. The PCM later sets P0441 (incorrect purge flow) or P0496 (purge flow during non-purge condition). Secondary effects include a rough idle right after start-up and, if the canister has been saturated with liquid fuel from repeated overfilling, a plugged canister that damages the replacement valve.
