Code P0401
I own a 2007 Lacrosse that I purchased last June with 36K . A few weeks ago the CKL came on. I hooked up my scanner, and it threw code P0401. I pulled the EGR, checked everything and sprayed it full of WD 40. After letting it sit for a couple of hours, I blew it out an reinstalled it. It was fine for about 2 weeks, the the light came on again, P0401. I went through the cleaning process again, same results. The engine runs fine. I am thinking that my only option is to replace the EGR, even though there is no guarantee that will fix the problem. Any suggestions?
