220cummins Posted November 5, 2015 Share Posted November 5, 2015 Did it tear up any CAC hoses? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/42495-08-pinnacle-lost-power/#findComment-310084 Share on other sites More sharing options...
Challenger Posted November 5, 2015 Share Posted November 5, 2015 Any codes? Maybe you mixed up some wires while repairing them? If I was going to guess, I would say you probably tore up your electric fan wires (assuming you have this fan), maybe the EGR diff pressure sensor wires, and the boost pressure or intake air temp sensor wires (this is the sensor on the mixer tube, its even the pressure sensor or temp sensor, I get these 2 mixed up). Any one of these could cause a limp mode and prevent a regen.
