P208A Reductant Pump Control Circuit/Open

[firefighter_2000]

Just got the code P208A Reductant Pump Control Circuit/Open. 105k miles all stock. I’ve tried reading & this doesn’t come up much. Best I can gather it’s either the pump itself or the DEF computer.
Anyone know what the most likely problem is.
Deleting is not an option I’m willing to do right now.
How difficult are the pumps to replace?
Any advice is appreciated.

I would unplug and spray some electrical contact cleaner on the connectors at the DEF pump....I remember reading someone having a similar problem...clear code and try it again...worth a shot.
