Hello and welcome to JustAnswer! I'm Nick and I'll be helping you out today. You'll have to perform a complete regen to get the code to clear after doing any work to the aftertreatment system. In most cases you'll need Cat software and a dealer password ***** initiate the regen.

Well there are many possible causes. It could be anything from a fuel filter to a sensor to the ARD head. It takes a good amount of testing by someone who really understands the system. There are not too many technicians that work on Caterpillar regen components and that do a good job!
