Engine/Transmission (1998.5 - 2002) Reading some codes

[Truckie]

I need some help trying to find out what these codes mean, and are they bad. I have a full set of gags in the truck along with the Edge Comp. I just found out how to check for codes. I also just put the Edge Comp and new lift pump on last Thursday, I only ran the lift pump I got from Dodge bout 3 weeks, and now put one on from Cummins. Here are the codes I got, I hope someone can decipher them fore me. Thanks.

Mike.

The codes are. p0122, p1693, p1687
