P0445 Evaporative Emission System Purge Control Valve Circuit Shorted Low
The P0445 code means the circuit of the EVAP purge valve is shorted, with more current than normal or a path to ground. Check for a shorted coil, a chafed wire or water in the connector 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.
