I'm going tomm to hopefully purchase a 01 2500 with 140,000. I'm wanting to run the codes before I sign any papers and I've been trying to search and find out what codes to look for and what they mean but the only lists of codes I can find are for after market comp. Are some of these codes compatible with the stock unit or are there seperate codes. Thanks guys!

 

complete code list can be found at the end of this document

The only one that you really need to worry about is the P0216 code. That means that your very expensive injection pump is dead.
