P0444 Code: EVAP System Purge Control Valve A Circuit Open
🟢 Low severity · drivable
Safe to drive — it's an emissions circuit problem, not an engine problem. Fix it before your next emissions test.
What P0444 means
The purge valve, which lets fuel vapors from the charcoal canister into the engine, isn't getting any electrical current because the circuit is open. The valve can't open, so fuel vapors aren't purged as designed.

- less common: Blown fuse or bad relay
