ISX15 ECM

[Hennessy]

I just wanted to say thank you to some of the members on here. your opinions and your knowledge helped me in a big way. UPDATE........ so they finished my truck, and since there was no one there when i picked it up, they left the keys for me on the floorboard. After starting the truck, I immediately got a stop engine light on, followed by 2 yellow lights. Error code 3214, 1922, 1921, and 2 other codes, and the last code was for my aftertreatment diesel engine pressure switch (forgive me, still a newb here). Had to replace a inlet nox sensor ($711.63) and tried to clear the codes but still could not. Another one of the codes had to do with a fuel pressure sensor short. After a few hours of banging my head on why its idling so rough, I decided to look up the sensors and test them. The very first connector i tested, became the whole problem. It was burnt on the inside and was causing every problem i had. I cut out the connector, spliced in a new one from the local hardware store with butt connectors and heat shrink tubing. After that I was able to clear all the codes and hit the road again.
