Looking for someone to help me debug some of my recent error codes.

The main recent one that’s got me concerned a little is this : 1B5101 terminal 15_3, line by CAS, electrical: Short circuit to positive

Now I have recently installed a JB4 & Methanol kit which requires a spot in the fuse box under the bonnet (nsf). But the whole system works as it should with no blown fuses.

But I have also had a upgraded turbo installed, but I can’t see that being a culprit for that kind of error code?

Now the other ones are :
1A2803 No Description Found(which is fine because there is no PPF now��)

1B5101 terminal 15_3, line by CAS, electrical: Short circuit to positive

10890C No Description Found (intake air temp sensor, will investigate further, is this the one by the filter or the one on the charge pipe?)

12152F No Description Found(guessing this is because of the bigger turbo which hasn’t been mapped to suit yet?)
