Order of inspection
P0448 Evaporative Emission Control System Vent Control Circuit Shorted Low
The P0448 code indicates a short in the EVAP vent valve circuit: the current is higher than normal or the circuit is grounded. Check the fuse, relay, connector and wiring before replacing the valve, because they are the most common cause. The code usually does not affect driving.
