I got a P0401 and P0443
My ses light has been going on and off for the past couple days and I finally got the codes pulled today. I got a 0401 and a 0443.
The 0401 looks simple enough to narrow down, from the info in in the tech info section I need to clean the egr and possibly replace. The information on the 0443 code honestly confuses me. It says something about a purge control circuit and further information indicates a possible problem somewhere between the pcm and the evap canister (I think).
Im just trying to figure out if the0443 code could be caused by a faulty or egr or possible carbon build up. It seems as if the 0443 code is more of a voltage problem but I just want to be certain.
