I had the same code. I cleaned the throttle body and cleaned the EGR ports. The EGR ports were completely stopped up. After cleaning EGR ports, I cleaned the IAC. I put it all back together and no more p0401 code. I did this about 3 mths ago. Fixed my problem.
Good article on cleaning throttle body and EGR ports.
