I have a 2007 3500 with the 5.9

I was driving on the highway at 120kmh the check engine light came on and lost power and ran ruff like a gas job with water in the gas. I pulled over and checked the coades.

p0206 injector 6 circuit open, p0483 cooling fan speed, p0201 injector 1 circuit open, p2149 fuel injector group 2 supply voltage circuit open.
The next day it added two more coads p0306 miss fire on 6, p0202 injector 2 circuit open.

Two days later I took it in to Dodge the check engine light was off and no coades came up and ran fine. Dodge checked the computer and found the coades cleared the coads and told me to come back in a week for a fuel system check.

A hour later the check engine light came on again with coad p2149 fuel injector group 2 supply voltage circuit open but still ran fine.

I dont see how all this could go wrong all at once then clear.
Anyone have any ideas or had this happen to them.

I don't have any personal experience with this particular incident, but lex parsimoniae says that the simplest answer is most often the correct one. Which makes sense in this instance. It sounds like some of the wiring leading between the ECM and these various sensors/systems had a temporary short. Could be a fray, could be water in a connection, could be something more serious. I'm sorry I didn't give a definitive answer, I just wanted to make the point that when working with wiring and or computers there is usually a centralized source to the problems and hopefully a centralized problem its self. Hopefully one of the older mechs will chime in with some experience. good luck.
