So I bought a 155,000 mile 2005 Pathfinder 4.0/auto 4x4 from a trusted guy who said he had it checked out and had a bad ECU.
So I have a replacement installed and grab the Autel MS906 scanner and turn the key. Initially get a no start. Do the Key re-learn procedure and it fires up and is running fine.
However, It is running in limp mode and getting P0605 and P0507 so I still need to do a re-learn as it idles at 1200rpm or so and is basically in a limp mode. I don't think I can reflash my VIN onto the new ECU as when I scan it, it pulls up the original VIN on the new/used part. My scanner is able to change a VIN on a dodge truck I have but apparently not this Nissan.
Think the relearn is all I need and would clear both codes or is P0605 a bigger issue(such as dealer reflash or another ECU problem?)
