Have a 2007 Dodge 3500 diesel that had the check engine

Have a 2007 Dodge...

Have a 2007 Dodge 3500 diesel that had the check engine light come on. It through 1 code P0131 and through P2A00 twice. Also note that the ECM on the truck was recently replaced.

Mechanic's Assistant: Does the light stay on, or does it blink?

It came on a week ago and went away, and it came on again over the weekend. I believe it just stays on.

Mechanic's Assistant: Are you fixing your B3500 yourself? What have you tried so far?

Trying to decide on whether to do it myself or not, have not done anything yet.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I believe that's it
