UPR shipped me a cable with the check valve backwards so be sure they are the right direction. There is a tsb about this code also that you may want to check into. I wouldn't just clear the code without checking it though.Just got the P04DB code and CEL last night. I installed the dual valve CC 2 weeks ago and the CSCC this past weekend. I double checked my connections and everything looks good. I've already gotten a little accumulation in the dual valve can and I'm pretty sure my check valves are in the right direction, but I'll double check. I may just end up having Adam turn off the CEL in the tune. Still annoying though.
