So I'm sitting at the dealership the 2nd week in a row now. Started up after walking out of the store and threw a P063d code today
Have been having issues the last month or so with voltage issues that I've posted questions about
Last week
Alternator tested good
PCM no faults
ECM no faults
Wiring no issues
Sensors all appeared good
The code today was the first code for this issue so far
Waiting to see if it's an intermittent alternator issue or worse. Hopefully something as minor as bad connection even though they are tight on new batteries
This isn't the first problem with the Ultra since installing last year. Depending on the outcome of today's visit it may be removed from the truck
