Hello today my friend got a code scanner and my truck came up with four codes im going to wait to see what they are tonight when my friend calls me and another thing its weird my truck has alot of power and runs perfect im wandering why i would have codes when my truck runs perfectly fine?

 

it could be that they are codes from a past problem that just never got deleted outta the computer

 

if i deltet them and they come back then that means that the codes are current?

the codes i got were p1682, p1693 is the fault in the busor pcm/ecm interface. then p0234 over boost, and then p0234that means i set the same code off again. would i know if the p1693 code was showing up how would the truck act?

 

Have your alternator tested.
