P0444 Evaporative Emission System Purge Control Valve Circuit Open Low
The P0444 code means the circuit of the EVAP purge valve is open, so the valve gets no current when the computer activates it. Check the connector, the fuse and the wiring before you replace the valve, which is an inexpensive part. A valve stuck open can cause a hard start after fueling and a rough idle.
