My wife has a 2006 Durango Limited 5.7L

Recently through a check engine light.

read on here how to get the codes to pop up in the odometer and I spent about 15 minutes trying to get them to appear.

Suddenly when I was just about to give up, it showed up, but didn't do the DONE portion, just a long ---------- line .

Now, before I tried this, I did go to autozone and have them code read it, and they found nothing.

So, is it possible that this code had self cleared at some point, then reappeared?

I tried to get it to come back on via the "off/on" method but no go after that weird showing up. So I decided to just do a reset via removing the battery connection and will see if the light comes on again.

Anyone else have issues getting the code to come up?

Am I going too fast / slow when doing the On/off back and forth?

 

Do you remember the trouble code number that came up?

the one code that did pop up with P0406 .

Got a thread about that elsewhere, with my wife driving the vehicle after I reset the check engine light and its off for now. I may try my first real car repair here myself by replacing the EGR.

 

lights back on again, so will probably change out the EGR Valve or clean it out.

Anyway, still having one heck of a time to get those codes to show up. Anyone else have some tips?

 

Auto zone will pull them for free,

funny thing is that when I went to autozone the first time, no codes showed up. I did the on-off routine when I got home from there and then a code showed up. I am going to do that again today, and also probably swing by autozone as well to reconfirm prior to the NFL game tonight.
