The 25 is for idle air control circuit prblem, likely a
dirty idle air control motor.
The 47 is for battery voltage too low. Dakotas are
sensitive to battery voltage.
The low voltage may be causing the ide to fuctuate
giving the code 25. Get your battery tested.

OOPS! I transposed the numbers!
Neither number activates the CEL except 45 on California
models.
If the truck runs okay I wouldn't be concerned.

I'm beginning to wonder if you have a cracked head or blown head gasket. Are you losing coolant? Oil?

How is the intake plenum gasket? Is there oil on the floor of the intake when you look down through the throttle body?
