P0444 on Hyundai
Evaporative Emission System Purge Control Valve Circuit Open
P0444 on Hyundai vehicles indicates evaporative emission system purge control valve circuit open. Au7o has documented this code across 1 Hyundai model — most commonly on Accent. The PCM detects an open circuit in the EVAP purge control valve circuit—no current path when the purge valve is commanded on. Typical repair costs on Hyundai range from $80 to $450, depending on the specific model and root cause.
Common Causes of P0444
- •Open/broken wire in the purge valve circuit
- •Failed purge solenoid (open winding)
- •Disconnected or corroded connector
- •Blown fuse feeding the circuit
- •Faulty PCM driver (rare)

Hyundai Accent(1 issue)
- 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 Hyundai Forums threads on this go back years and turn up a second cause besides the valve itself: outdated ECM software, addressed by a Hyundai service campaign software update, which is sometimes the entire fix.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.
