KW T660 CM871 aftertreatment issue

It very well could be the eBay and Amazon sensors. We have been catching hell finding a lot of sensors and have actually had to order a few used ones from vander haggs to get the trucks by till the ones we order from dealers come in. Your exhaust temps should reach way over 250 degrees just with the truck idling. That’s where you need to begin looking. It’s not going to initiate regen with exhaust temps that low.
