RE: code p1391
I would disconect the battery. Hold down the brakes (about 30 sec) so the light would normally turn on. This will reset the system. Replace the cables and you need to drive the thing about 45 miles for a complete reset. During this reset it is nice to cycle the ignition 12 times.
Now I don't know the code you have there. The p1391.
This is not a code #. I have posted the Index here at the begining 1st generation threads. https://dodgeforum.com/m_614377/tm.htm
Lets re-read your code so we can match it up.

98 Dodge Dakota
I have a 98 Dodge Dakota in which they rebuilt the top engine portion under the used vehicle warranty when I bought it. Since then, the "check engine ight" has been lit and the code it gives is P1391. The truck starts perfectly and runs great even in very cold weather. Any input as to what it can be? I live in NY state (unfortunately) where you fail inspection when your check engine light is lit. Thanks for any input and help.
