Good day all, So one day my Dakota' check gauge's light comes on and volt meter drops to low, I check voltage at the Alternator and at the battery, both are reading 11.86 volts, so I replace the Alternator with an original equipment one, And check all the connections to make sure they're clean in type, I drive the vehicle around the block And the same exact thing happens again, at home I check the voltage and its exactly the same as before, So now I connect my code scanner which say no codes, now I check the on board scanner and it produces the code P0622, any ideas? Do you think if I changed the PCM it might alleviate the problem, I'm 66 years old I worked on a lot of cars in my time new and old This one is very baffling I need This vehicle to run it's all I have, Any help with the situation would be greatly appreciated,

So I replaced the battery and nothing changed, Today I am replacing the new alternator under warranty as the reader says that the regulator is not working

Except you had the same problem before replacing the alternator... I'd look for bad grounds at the alternator, bad battery cable terminals, anyway I hope the new alternator fixes it for you but I'm not optimistic.

Check the Battery Temp sensor. Located under the battery.
