The P0401 is a fairly straight forward code pointing to a problem in the EGR System. The EGR Valve is located on the driver's side, rear of the engine. Carefully inspect the EGR Pipe and the rubber lines for any crack, holes or leaks. If the visual inspection checks ok the EGR Valve Assembly will need to be replaced. While replacing the EGR Valve, it's a good idea to try and remove as much build-up from the ports behind the EGR and EGR Pipe. Use some throttle cleaner and a flat blade tool to scrae out as much as you can, without letting too much fall back inside.
