had this bus come in with all the check engine lights on def light and def gauge yelloe light on with gauge flashing red pulled codes and there wher a bunch first there was 4677 4572 3868 def tank temp level and quality now i no there is a tsb for these about the control valve being stuck open but there are also other codes which is making me think its something else the codes are 6688 2771 3232 4151 4152 the are all update rate abnormal for aftertreatment nox sensor inlet and outlet dpf module and scr temp module some of the diagnostics say possible power lose or terminating resister issue as anyone run accross this and could some how the def control valve be cause this also where are the terminating resistors located
power issue to your aftertreatment relay or from that relay to the aftertreatment devices, they all share power except for the inlet nox(sensor in pipe after turbo) plus its a C2 its always a wire , junk
