P0443 on Hyundai
Evaporative Emission Control System Purge Control Valve Circuit
P0443 on Hyundai vehicles indicates evaporative emission control system purge control valve circuit. Au7o has documented this code across 1 Hyundai model — most commonly on Accent. 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 Hyundai range from $80 to $450, 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)

- EVAP Canister Purge Control Solenoid Valve Sticking (P0441 / Stalling While Refueling)2006-2022
The canister purge control solenoid valve (PCSV) on the Accent sticks partially open or fails to hold vacuum, so fuel vapor flows into the intake at the wrong time. The classic owner pattern is a check engine light with P0441 (incorrect purge flow) plus the engine stalling or stumbling immediately after topping off at the pump, and a slightly rich, rough idle. Hyundai Forums threads on this go back years and turn up a second cause besides the valve itself: outdated ECM software, addressed by a Hyundai service campaign software update, which is sometimes the entire fix. The other frequently missed contributors are a saturated charcoal canister (from repeatedly overfilling the tank) and cracked purge lines.
