I was towing a 2500+ pound load today and my check engine light came on. When i shut the truck off the light went away until i pulled a hill again. I got home ran the codes and got DTC 92-#2 cylinder balance fault and DTC 78 Turbo waistgate solenoid. I know why i am getting the DTC78 i got rid of the vacum pump and put a manual waistgate accuater. But the DTC92 i have no ideal what this mean or what would cause this one. If anyone could help me out and let me know where to start on this on. I googled it and got a bunch of stuff about a broken crank kinda has me worried ALOT about this on. Besides it seems to laking a little power it seams to be running good.

 

if light came on pulling a hill may have weak LP and you where defueling need see what the psi going the IP
