Back in September, I had 2 codes, which are both related. They are:
P0105 and P1105
I never fixed them and just ignored it.
So...I haven't driven my Maxima in about a month. I started her up today and took it for a spin. I passed an Autozone and decided to stop by to pull the codes, to see if I still have the same codes.
I still have those codes, and 2 new ones
P0400 (EGR system fault) and P0600 (AT Communication Error)
I have no idea what these mean, as I am not mechanically inclined. What do they mean? And typically, are they costly/trouble?
