dead accelerator pedal, P0652 ????

Anyone I have an issue and would like to know what everyone thinks.
This is on a 2009 6.4
Here’s the deal. Yesterday I was installing a ridged 20” light bar I had to rearrange some wiring for my winch in order to put the light bar where I wanted it; I may have made a dire mistake.
Once I rearranged the winch control box to where I needed it to be I found myself short with the power cables, in my wisdom I wired the positive cable to one battery and the negative to the other. Red to red driver’s side black to black passenger side. I thought this would be OK; Did I wire it to 24 volt? The reason is once I started the truck it run ok, but I had to shut off the truck and do more, and now when I start the truck I have high idle 1450 RPM and a dead accelerator pedal, The truck is Spartan tuned with the 275 tune and has been for 15 months, No DPF, The codes it is showing are
P0652 sensor reference voltage B Circuit low
P1000 systems readiness test not complete
I tracked all the wiring I did and can’t see anything that may be shorting, All I can think is I somehow sent 24 volt into the truck and cooked something.
Anyone have any ideas?

Check your fuses in the under dash fuse panel on the passenger side. The fuse is a common blown problem when no throttle response.
